If you have a civilian P320-M17 the removal process is slightly different. The rear T15 screw on the surplus gun is instead a spring loaded pin on the civilian model. Simply use a punch to push the pin in, and while you have the pin pushed in, carefully remove the back plate. Then carefully remove the pin/spring and extractor. You don't need to remove the striker. All you have to do is use a 3/32 allen wrench and remove two screws on the underside of the slide that are securing the sight plate. They were put in by the factory using blue Locktite, so they will be tough to remove. Push down hard to you don't strip them as you are breaking them free. Once you remove those screws, the sight plate and rear sight come off.
Thank you again for all of the intricate and clearly explained content. Having watched your videos repeatedly made me unafraid of taking apart the two new P365s I bought yesterday for my wife and I to carry. I stripped them right down, cleaned and lubricated them, which I’d never have done without you “holding my hand” in a sense. I have no history with guns so this is all pretty new. All my best!
Sig Sauer Guy Well, I can’t thank you enough. You’d have made a great teacher; maybe you are. I taught at Phillips Exeter for 25 years, so I know what makes a pretty good teacher. Best Regards.
Thanks for the video showing how to take the optics plate off. Wondered where that screw was hiding. At 6:52 mine's doing the same thing yours is, not going into battery when you don't fully let the spring carry the slide home. I saw a 1/4" of guide rod sticking out near the end
The two screws that hold the rear sight plate on are 4-48 socket head cap screws. A 3/32 allen socket is the best tool for removing the screws - not a T15 hex
That is correct for the M18 and possibly civilian M17 but he is working on a military spec M17. It is either a Milsurp M17 (as I have) or a commemorative edition which also has the same PVD coated controls. The M18 uses 2 Allen screws to hold the rear sight on. They are different designs. SigGuy is correct in it being torx
I have questions. So the romeo 1 Pro and Romeo Zero have the same footprint withe the exception of different screw sizes. I recently bought a Romeo Zero Elite and included are screws which will allow it to mount to the R1P footprint? Second question, the Pro cut slides have R1P and RMR holes, can an RMR be installed without the expensive filler plate CHS sells?
Todd The GunGuy slow and steady wins the race. Take many pics to reference. Practice makes perfect. Maybe just go a little further each time until you feel comfortable.
@Sig Guy I'm working with a USGI M18 ..... from what I've read, its only compatible with Leopold DetaPoint and Romeo 1 optics.... do you know if thats the case ? I'm tring to understand what the difference(s) are in the adapter plates (RMR / MOS & whatever else there is) so I know what other types of optic options might fit. Any help is appreciated.... thank you for the video, I'm guessing removing the rear sight plate should be the same for the USGI M18.
These things are trash on the military side. Thank you for making this video. You're saving me the headache of the flipping through the manual. I hear a lot of great things on the civilian side, though.
Hello, after watching this video it appears I can easily install the new Romeo M17 optic on a civilian issued M18 by simply drilling a hole and recessed area for the T15 screw. What are your thoughts?
Is the slide finish different on the military surplus version of the M17 then the civilian versions??? It looks to me like it may be… that’s one of my disappointments with the M17, that finish. My finish has been worn off just from a few range sessions using an Uncle Mike’s nylon holster. I think for the amount I paid for this gun, it’s finish should stand up a little bit better. Otherwise, I love it… I chose it over Taurus G3, safety was hard to release, Glock 19, couldn’t reach and activate the mag release well, and P365XL, (which I did end up buying one) for not being able to reach and release mag easily… I’d have bought it first if I new they had aftermarket releases. But I loved the M17 cuz it just fit my hand like it was made for me. I wish they’d have put a mag release and safety like is on the M17 on the P365XL. The M17 mag release is more squared off than the P365XL’s that kinda follows the profile of the grip. Oh, and the M17’s has texture. The M17’ s safety has a more pronounced lip and is flatter & wider than the P365’s safety. Not saying use the M17 sized safety, just it’s design shrunk down to fit the 365. I don’t know if anyone has had this problem, but if you put sideways pressure on the 365 safety it sometimes binds up. I believe that the design of the M17 safety would prevent that. Oh yeah, I digress… finish!!! I’m really disappointed with this finish!!! Anyone else have theirs rub off???
I suggest some white or yellow tape. Check your camera feed on your monitor or phone and see where the edges of the camera coverage are and mark that area with the tape so when you're working you can know when you're on camera or when just your fingertips are showing.
I got the sig p320 m18 California neutered version I need a plate for it to fit the holosun 570 but plate needs to have rear co witness suppressor sights
I own both the surplus, and the commercial 320/M17- I have allways wondered why they chose to use different methods of attaching the rear sight plate ( one screw vs two screws) And a different rear sight design, and lamp color. They should use the military rear sight on them all. I have had two loc-tite the 2 screws on the civy model twice. Seems like differences for no real good reason. Holding off on the 320/M18 until a commemrative or special edition comes out closer to the actual military one.
Is that an early model? Mine does not have the screw that yours shows to remove the sight and plate, mine has Two screws holding them on in the same holes you use to mount the new sight
Wow there's only 1 screw holding the rear plate & sight assembly to the slide for the surplus edition? I looked this up because I am having trouble getting the two screws into the rear sight for the standard M17, which is a two piece assembly onto the slide. They must have changed the fixture design for this model. The sights came loose after about 1000 rounds and I don't like having to get loctite into the threads, as people have recommended to me. Not really happy with these sights and may have to contact Sig to get a replacement.
Patrick Kudo had to loc-tite those two screws twice on mine... didn’t degrease good enough the first time. But there is no keeping it tight without the loctite. Not going to happen.
Great video! But maybe you can help with two issues I’m having. 1. After installing the Romeo 1Pro optic I’m left with the screw hole being exposed behind the optic. Am I missing something?? 2. I tried to lollipop the red dot with the front sight and the notch on the back of the optic but the red dot bottomed out and won’t go low enough. I haven’t put a laser boresight in yet so it may be a non issue.
The sights do not co-witness with the standard sights. You would need a higher suppressor height front sight if you wanted to get co-witness with a front sight post.
Hey Sig Sauer Guy! I just finished going through your videos and would like to say I'm a huge fan. I have a couple questions that I hope you might be able to answer. I am currently running a standard P320 and added the V1 factory flat trigger last year. I was thinking of adding the Apex forward set trigger bar, seeing as how it performed fairly well according to the data you posted in the video of p320 triggers. Can you give any anecdotal thoughts about this combo, since it wasn't directly addressed in your video (I saw V2 was)? This would be for carry, not competition. Also, do you feel the legion trigger bar or trigger is a significant enough upgrade over this combo? I know smallgunparts has both listed, and I'd be very interested in seeing how it stacks up to the other triggers you have! Thanks
The Apex kits are very nice. I have always been a huge fan of them. Most of my other videos are from last year. There are some newer trigger options available. Armory Craft will be releasing their 320 duel adjustable trigger February 1. I have been fortunate to have been using it for the past couple months. It is definitely a game changer. I would not invest in the Legion trigger. The Legion trigger bar is the exact same as the standard trigger bar but allows for a manual safety. I have posted a couple videos referencing Armory Craft if you haven’t seen those. The trigger is amazing.
My M17 does not have a torx head on the screw that you clocked and removed in order to access the screws inside that hold on the sight plate. On my weapon it is a beveled, but blank insert. It's black in color also, not FDE like the one shown in your video. My sights and plate are noticeably loose but I'm unable to remove that holding pin assembly at this time. Any help would be most appreciated.
UPDATE: Found another newer video and the guy's M18 had the same extractor rod as mine, which is removed by simply pushing IN on it with a blunt punch of some kind, and then sliding off the rear cover plate as normal. Hope this helps anyone else who like me was puzzled about this initially.
@@BakedAndAwakePodcast my video is for the United States government issued M17. Apparently they think soldiers are not smaht enough to push in and turn lol. Yours is the civilian model. I made the video because those with the USGI model weren’t sure how to disassembly. Thank you for the support though sir. Glad you were able to get yours taken care of.
john grimm the new Armory Craft dual adjustable trigger. Remove as much pre travel and over travel as you went. 30% less pull weight also. Will be available February 1st 2020.
I own a P250 compact and would like to install a red dot site....I can't find any attachments to attach without sending to get milled,don't want to cut into the slide...and everyone has videos on how to unscrew a plate or dovetailed sites....P250 has neither...any solution to my problem?
The solution would be buy a 320. I know it’s not what you want to hear but you will be extremely happy you did. I own 3 P250s. There’s just no aftermarket support for them. Armory Craft is making a trigger for them. Other than that they are considered obsolete. After owning 320s now I wouldn’t hesitate to make the change to a P320.
So that is an authentic P3 20 M 17 that was issued to the military. The controls are used to be coyote before they switch to black. There was only a little over 5000 of these offered to civilians. They are still out there just a little more hard to find and a little bit more expensive.
@@SigGuy ughh they should sell those parts in coyote man, nobody sells them online? All I see is black black black , all I could find was the take down lever and back plate that’s it
@@stephenmartin3859 All you have to do is push down on that pin and you can slide the plate out. Also, the hex head screws to remove the back/rear sight post plate are T10, not T15
As I understand: the Romeo 1 Pro will also fit. The new Holosun 407K and 507k models will apparently fit as well. But I don’t think they have been released yet.
Can anyone show me where this procedure is shown for the m18 model? Cause that torx screw on the back of the slide is diff on the m18 and I can't find instructions anywhere in the Manuel or the internet anywhere I'm receiving my trijicon rmr type 2 in today and have no clue how to ibstall
I can’t, for the life of me, understand how or why sig would have the rear sight attached to the optics plate. What year are we in? Almost every other gun on the market has done the opposite of sig and it’s helped us tremendously. When I first got my p365XL with the Romeo zero already on it I thought Sig would at least include the rear sight in the box. NOPE! Sig continues to disappoint in more ways than imaginable
