- Heckler & Koch Tutorial: LEM Trigger Explained.
Variants with HK's enhanced double action only Law Enforcement Modification* (LEM) trigger have no external decocking controls. The HK Law Enforcement Modification (LEM) trigger system combines the advantages of a cocked striker component (constant level of trigger pull from first to last round fired) with a double-action hammer system. Using such an enhanced trigger system consolidates ease of use and safety into a convenient, innovative trigger operation-one that reduces the chance of unintended firing. And in case of an ammunition-related failure to fire, all that is needed is an additional second or third squeeze of the trigger without the need of first pulling the slide back to re-cock the pistol. The enhanced LEM trigger system combines the reliability of a double action revolver trigger with the crisp trigger of a single action pistol.
I think my brain just peed itself.
Best carry trigger on the market. Love having a hammer to thumb over when reholstering in appendix carry.
The LEM is something you need to try out before you can fully appreciate it. It’s the best IMO.
I LOVE LEM triggers.... wonderful invention. I am more accurate at shooting my HKs with LEM triggers than I am with my 1911's (SA). Actually, I shoot the most accurate with my LEM over every handgun I have ever shot.
Not only that, but I feel its the safest way to carry a handgun.
I’m positive this video was being created around 4:30 PM Friday. The guy was trying to get it done and go home before 5. Please make your next video in the morning and talk a lil slower. Thanks lol
All my HK's are LEM'd, simply fantastic.
I’m a order the LEM trigger kit for all three of my H&K’s my P2000 40, USP9 and my USP40. Within the next couple of months.
I love my HK 45C with the LEM feature!
Love this guys video I had watched another youtuber's 7 minute slow drawl uhm, him and haw and didn't learn anything compared to this concise expanation
I have 2 versions of the P30, V1 and V3.
Never thought I would like the V1 light LEM so damn much.
It is the perfect balance for me.
It took me awhile to feel "comfortable" with it, but it is my always carry option. I have four USP Compacts, three all variant one, 9mm. .40S&W, .45 ACP....yeah I am a collector, but my forever carry, is the .45 ACP LEM. Once you learn it, you got it. I love my 1911's, but I love the versatility/action for this variant of polymer handgun is a game changer.....even years later
My head just exploded.
Excellent presentation and explanation! Thank you!!!
IMO the most creative trigger system on the market. Sig had DAK but did not pursue anything past that.
I still perfer the tranditional DA/SA trigger. But this seems fun to shoot, maybe good for competiting.
Absolutely.. I've never been a fan of those LEM triggers, I go with a traditional SIG P22x DA/SA trigger!
Of course! Because LEM sucks and is cheaper!
I have a USP9 LEM best purchase ever. I’m a order a LEM trigger kit for my USP40 and my P2000 40 this week.
This guys reminds me of those 80’s micro machines commercials with the guy that talks really fast.
you was impeached at shooting gun gun extremely quick accurate with no recoil their training I need to practice
torn between getting a usp expert or a p30ls. personally I like 1911s cuz of their single action and typically lighter triggers. the thumb safety doesn't bother me. I guess cocked and locked is just my cup of tea. (makes me feel like there's almost no chance of a ND and quicker/more accurate initial shot off)
Please release the VP9sk with a safety already.
What? Was I the only one to tell this guy to slow down?
You can’t tell a T1000 to slow down though
Me too! I felt like an unfreed brain plugged into the matrix, trying to receive a download on how to fly an MH-60.
Listen faster then, Slacker!
So it’s a passive double action single action that resets back to being a passive double action automatically when you let go of the trigger ?
Did HK have a contest to see who could run through explaining the LEM trigger the fastest and most confusing and you won? Your thumb was blocking the view of the hammer when you pressed the trigger in what I will call single action. While you did explain it I wanted to see for myself what it actually did at that time. Was a 2 minute video too expensive? I guess I'm not completely understanding how the hammer is pre-cocked when you first work the slide and load the initial round but then you say the hammer is cocked when you press the trigger the first time. No one is going to have stock on anything where I can touch and and be shown how it works so before I lay out cash that would equal roughly 1-2/3 Glocks, who by the way do a very good job explaining their trigger and safety system, I'd really like to know what I am getting.
I love that he has a Match Trigger. Or what seems to be like one with the stop on the back. Where can I get one for my P30L?
I was able to shoot a usp with the LEM trigger its strange but also very nice I would love to get mine upgraded its worth it.
It's just an auto decocker.. I'd rather have a manual decocker and keep with a 100% predictable trigger.. I'm sure it's fine, but I don't like a trigger that could change on me at any shot............ at least DA/SA is only different on that first shot. Striker fire is king anyway.
ya think you could have taken little longer to explain.....you tube doesn't charge by the minute
I understand..
Is there any differnce between the LEM and the CDA trigger? And if so what are they?
Can't wait to get an HK in lem, i got the SK V3 and am wondering if I could send it in to HK to get the LEM v1 installed. Also have a SIG P220 in DA/SA (don't plan on changing that) but I found one in a DAK (like the LEM) trigger and would love to compare, HK's variant seems a bit better.
Bill Springfield of Triggertech does a trigger job on all HKs.
Let me make sure I understand you. With the LEM variant trigger setup I don't have to holster my USP Compact cocked and locked and would still have the option to place it in the safety mode but there is no longer a decocker because whenever I release the trigger the hammer will go forward.
Yep
I still don't understand how it's effectively different from any other DA/SA pistol.
I think the idea is that if you don't allow a full trigger reset then it's lighter and basically SA, but once you allow a full reset (finger off the trigger) it goes back into DA mode... I think.
The difference is the hammer spring is cocked but the hammer itself is not. So the initial DA pull is lighter than other guns that have to compress hammer spring.
@Johnathan Celso I understand how it works, I just don't really understand why it is a meaningful improvement over using either a da/sa or a sa. Da/sa is safe and a lot of people like the long first trigger pull as kind of a safety feature, and the following trigger is going to be as good or maybe even better than lem. Carrying cocked and locked is safe and also has that good trigger every time. How important of a development is this for the market really? Was someone out there underserved until now?
@@Makingnewnamesisdumb With this, you're getting a long but reasonably light first pull, whereas with a DA/SA gun, the initial pull is normally much heavier, although the *length of pull* is basically the same.
Whether or not the LEM is as good (or better) than DA/SA or "Cocked and Locked" for the same gun is debatable.
I still prefer double to single, gives you more control. Seems silly to have the hammer spring compressed 24/7. Also, you can cock the hammer back to start in single action if you want but the heavy double action is fine if you know how to shoot and you can de cock your gun when ever you want. LEM seems like something noobs would like. And its def not as safe as a heavy pull but still nice you can put your thumb over the hammer when reholstering. When i shoot at the range i always pull the heavy double action first shoot and acurracy is just as good and when the gun goes into single action its like you cant miss and really fun, i like the transition.
"LEM seems like something noobs would like" and your comment reads like something a noob wrote. There's a reason most of us shooting HKs in USPSA have switched over to LEM. You can't pre-cock a hammer before a competition event, and the 10lb trigger double action is a huge detriment to speed and accuracy when fractions of a second are make or break times. Experienced shooters are comfortable switching over to a system that relies on them understanding the trigger break and reset points, quick enough on follow up shots to take advantage of that LEM reset point, as well as have confidence in their draw and aim that having a very light first trigger pull is a benefit, not a detriment.
@@collapsedsilence I'm not a noob but not a competitive shooter, im glad you posted though, i didnt know people like the LEM trigger. What i said was i like the regular set up since the springs arnt under tention year after year in a carry or home protection set up. Maybe i'll try the LEM trigger set up some time. I really jusy meant i like the regular set up, i also shoot revolvers and shoot them in double action like how you would use them in self defense so the double action pull is fine. I do understand where your coming from, Competitive shooting is a different situation but at the same time it isnt. Of all the guns ive shot i prefer the double to singe action no safty set up the best, seems the most practicle for if you have to draw your gun and point it with yoir finger on the trigger like a revolver, no accidental shooting and i like the decocker on a Sig, makes it feel like a Sig. I didnt realize the LEM was used a lot in competitive shooting though, i figured it was for dumb cops that cant shoot so i'll search for some videos on it.
@@nobodysreview6137 I would absolutely suggest *most* shooters to go with a V3 type DA/SA triggers, you're spot on. I'd also agree with you that to a novice just reading about it, the idea of a crazy light trigger just sounds better. But it isn't, and the reality is there's a fine line where the extremely light trigger weight double action and short reset on the LEM is beneficial.
It's pretty much exclusively competition shooters, shooters trained to fire off the reset on follow up shots (meaning holding the trigger for follow up, align your sights again, and when ready for a follow up shot slowly release trigger finger until reset and then pull) and law enforcement where they would always want a double-action trigger pull so every time they draw and fire the gun reacts EXACTLY the same so there's no thinking, prepping or planning during a high stress situation. That last situation is why it became the Law Enforcement Model (LEM) name.
@@collapsedsilence Thanks for posting this info. Question: my understanding is the V7 LEM from factory on USP 45 is approx 6-7 lb and what you describe is the lite LEM option. Is this your understanding as well? It may be that people that don't like the LEM have tried the V7 which is a heavier trigger pull.
So you’re admitting you pull the heavy first shot… but lem triggers are for noobs? Or maybe it’s for people who don’t want to “pull” the first (and most important) shot.
Never had a chance to hande... So is it like using da/sa but using the decocker (but it 'decocks' automatically)?
So.... this is tricky for me: Doesn't that make it double action only?
I really wish I lived in a free (er) country.
Never let them take your guns!
If I buy a HK45C V1 can it be converted to a V3? I know you can convert a V3 to a V1 but I wasn’t sure about the other way around.
So....rookie here my new p2000 I need to cock hammer for 1st shot.....then the action will recock hammer each time and gun will operate as a single action as long as I dont fully release the trigger??
I'm a member of the LEM Master Race, but I don't feel this cat communicated, or exhibited, how the LEM triggers actually work. He failed to display how the LEM trigger works prior to racking the slide, versus the actual use case of racking a round into the chamber for carry or duty purposes. If you're on the fence about a LEM model, pull the trigger. It is not a DAO pistol! All hammer fired weapons should mirror HKs LEM system and I'm not even and HK guy. I'd love an M9A3 G model, but even then, there is zero advantage of having a decocker only lever with that awful 12 pound double action pull at the start. Go LEM.
Yeah, I agree that he didn't communicate this clearly. His thumb was also blocking the hammer.
Also, a 92G would be 🔥 with an LEM trigger. In fact, like you said, they can finally get rid of that God awful slide-mounted safety/de-cocker that literally no one likes.
I also want one of those new Performance models(I think they're called? The chrome looking ones with the frame mounted safety and the beavertail?) as well. In fact, if they made those with a long upswept 1911 style beavertail I wpuld probably have one already.
How short does it make this trigger reset lol with gray guns trigger system?
After an extensive nationwide search, I and my gunsmiths have been unable to locate a V1 Lite LEM trigger kit for a USPc 9mm I bought new in 2000. Any suggestions on who I might be able to source one from? Thank you in advance for your assistance.
How do I uncock the hammer without dry firing??
From what I gather, it bascially goes to a "double action like" trigger pull when you fully let go of the trigger... "that feels single action"--- Sounds pretty muddy to me. Is it cocked or isn't it? Is it in double action or isn't it? Just give me a DA/SA for half the price and I'll be much happier for both reasons.
@jason tays Incorrect. The LEM version doesn’t have a Decocker. Only the DA/SA version does.
tres bon
What do you recommend for me? I just purchased the H&K P30 SKS V3.
so its a double action pretending to be a striker fire?
Can I keep the full hammer with the LEM upgrade?
Can you get the LEM modification on the USP's??
Yes.
You can! Go checkout H&K Parts.net
Was anyone else hoping it would be Hans from the German Factory?
Which is better P30 LEM or a P30 V3?
My school banned your website and I was upset
Fast Forward video
Any guess which caliber he's shooting? Is so flat I think it's a 9mm. But he is the pro of pros. .40? I don't think so. I just bought this gun. It is sweet. But I want to know... is there no way of decocking the damn thing? You can't even reliably reach over the top for pinch/ lower on the hammer. I don't always need a handgun 'ready to go. There will be times that I just wanna 'put her in neutral'. Ya know.. like at the range, with a newb, trying to show them something. Of course, I should bring one of my many hundreds of other guns better suited for newbie instruction. But, today, this is all I happen to have with me.
The “cocked hammer” is internal on a LEM.
What advantage does this trigger system give one over the DA/SA or striker fire?
So with the LEM, the trigger pull is lighter than without the LEM, right ?
Im wondering if the travel with LEM is long, since the hammer have to move back at every pull. It's like a like a double action without the weight but with the same long travel.
Nekkar negative
Ненадёжно ведь.
What pound trigger pull is the LEM variant.
I have P30 v1 which has a trigger pul of 4,5lb
That particular gun does not appear to be LEM. Wrong hammer, over travel screw, and thumb safety would indicate it is not.
LEM hammer can be both in bobbed and spurred variant (spurred variant is rare in US, common in Europe). LEM is compatible with P30S and P30LS with manual safety and levers stay in place and still works. Overtravel screw can be added to any HK trigger - 10 min job for HK armourer. I'm sure HK USA has those screws laying around. Some people were successful in modifying USP match trigger tongue to fit into USP Compact, P2000 and P30 as well.
But you had good eye - dynamic shooting scenes (at least some of them) show SA/DA variant in use.
I shoot P30L with V4.1 LEM in competition and I love this setup. Can not fit overtravel stop to mine as IPSC Production and IDPA SSP rules prohibit this.
Montrala you sir seem very well informed. I just got a insane deal on a v3 ?? p30 after lusting after a lem one for years. Can I convert the da/sa to the light lem version? Or add a safety to the v1? Its just the da is pretty heavy and while this was supposed to be a range gun but I like it so much I'm considering carrying it and that first shot is the most important to me in that role. Hopefully its the only shot. Also I'd love to shorten that reset. Super interested in this v4.1 you mentioned. I need to do more research and reading.
Preston Watts In P30 V1 designation depicts light LEM trigger. Parts needed to convert V1 into V4.1 (V4 CH) are listed on mu blog.
Montrala thank you for the info. I later went back and edited my comment because I said my p30 was a v1 when in fact its a v3. But your blog has that covered too. Great resource for a new HK owner. montrala.blogspot.com
Walther Creed has same shit but might even be better
Is it on the mk23?
No
slow down Sr please
I recently purchased a P30L V1. I have two questions: Do they usually come with 10 rnd mags? and I noticed what looks like a safety lever on the one in the video. Was that added on afterwards or is it available to purchase with one?
Thanks.
Thats the S model that comes with a safety.
I figured. But when I purchased mine, they told me there was no Model S with the LEM trigger. Do you know if there's a way to convert mine? And thanks for responding to my question.
No you have to get the gun with a safety and then switch out the springs to make it a LEM type trigger.
Okay. Like I said, I was told by the gun store that there was no safety offered with the LEM trigger...it's okay...I love it...I actually got two of them...
To each their own
I would ask you to calm down and slow down but I know it’ll be hard cause you’re a T - 1000
Sounds like HK caught up with Para Ordnance LDA?!????
Gentry Tipton: I’m sorry. The LEM came first. The Light LEM came shortly after. And, the progenitor that made it all possible, the HK USP is now celebrating its 25th anniversary this year.
H&K was way ahead of it time when it comes to semi-auto pistol design and engineering.
I’n this video, he demonstrates the much newer P-Series design. However, the LEM was originally designed for the USP model, which for my money, is still the Heavyweight Champion of the world among all other polymer framed semi-auto pistol designs over the past quarter century.
Next time, indica and not sativa!
TLDR: german engineering.
Other videos explain it better
Poor job
You talk to fast!!!!!
He's talking wayyyy tooo fast
am I the only one who doesn't like this trigger? I have one on my usp and I do not care for it
So change it if you don't like it.
+Len M. I plan on it eventually just right now it's not my highest priority. btw do you know if a safety and decocker can be added to v7 usp?
I know many who do not care for it. I like it, especially the V4.1 CH.
John Wick Supposed to be some version of LEM that has shorter initial trigger travel. Then you have the Todd Green Special, where you put in the heavy trigger return spring to lite LEM, which gives a "kick" to the trigger reset. Would recommend checking HKPro for more details with various options.
a lot of you need to upgrade your brains if you think he's talking too fast.
People like LEM only if and if only(Law school logic if you don't get it) when they cannot find or cannot afford a SA/DA+Decoker+external safety HK😂
Because grapes are too sour😂
Lame trigger variant.
While this video contains important info., the presenter, a competitive shooter and representative of the H&K co. just speaks too fast. He does the same in all his H&K videos.
He offers us much insight. but it could have been better presented.
So it's just a DA/SA with an auto decocker... cool
But hammer spring is cocked. So light pull in DA.
Why does this guy feel like he has to talk like the Micro Machines guy? Jesus, maybe choose someone for a tutorial that talks at a normal speed rather than someone who is on speed. 😂. I had to watch the video like 4 times because of this tweeker. 🤦♂️
