- This video is a basic review of my H&K VP9. Watch as I do some target shooting and run into a bit of an issue.

Polish the ramp with green jewlers rouge and cloth dremel bit
Feed failure is a really common problem in all kinds of weapons, when the manufacturer skimps by hiring foreign "engineers" instead of legit First-World educated gunsmiths, and/or skimps by using poor quality materials to construct the magazine. The Jennings 0.25 handgun has the same problem, and so did the version of M16 that was standard issue during Vietnam. You can look that up.
While troubleshooting my mom's Jennings, I came up with the same thing @thepatriotsrock2 did -- the feeder ramp is badly engineered. It's just a hair too high, so even rounded-off common lead slugs just jam up against it when the action catches the rim and pushes the bullet from the magazine. THIS IS WRONG!!!!!
The real problem is THE MAGAZINE. The springs that push the platform up (thus exposing the next round to the action) may be worn out, or may just be garbage from the factory due to low-quality materials and amateurish manufacturing. They're supposed to push the front/nose of the bullet up significantly higher than the back/rim, so the rounded slug is perfectly angled in-line with the feeder ramp, but the magazine's box is slightly too long for the bullets so after you've loaded the mag the bullets can shift forward in the box and then the slug is no longer lifted into the position it needs to be. Instead, the forward spring rests slightly behind the slug so instead of ready to feed, the slug is just ready to get wedged between the sliding action and the end of that feeder ramp.
In Vietnam, US Soldiers armed with M16s got into the habit of taking a loaded mag from a pack, banging the back end of it against their helmet (or any hard surface) a few times, and then slapping it into the receiver. This migrates the bullets backward so the rims are flush with the back edge of the magbox. Whether this works with your particular mags or not depends on exactly how tight those springs hold the bullets against the curled-over stops at the top of the magazine box. Grinding down the feeder ramp (even just to round over the edge so rounded slugs slip onto it easier) may or may not fix the problem overall (I'm betting not)... and may in fact result in a misfire which makes the gun blow up in your hand, and if you're very lucky leaves you more than 90% function in that hand.
It probably took Colt 10-20 years to fix the M16's magazine and receiver sizes to contain the bullets where they need to be, but at least they did the troubleshooting and R&D to give our soldiers a workaround and then they did eventually get it fixed. Or maybe they fixed it immediately but only eventually got the new design into circulation.
Your VP9 was introduced in 2014, allegedly after 5+ years of R&D, so H&K (a German manufacturer) specifically designed this VP9 for law enforcement usage and they used outdated gunsmithing designs which led to this operational failure. I wouldn't have anything by H&K if you paid me to store it. That's just suicidally stupid if you have any fantasies about using the firearm for self defense purposes.
Seems like you’re well educated about firearms so I’ll have to take your word for it that what you say is true. However, there’s no way I’m taking a grinder to my gun. Seems weird that, so far, only 1 type of ammo causes this problem. I’m going to try more and see how it goes. Thanks for watching.
@@badbloodoutdoors1874 Hey there. I think you failed to click READ MORE on my post XD
What got cut off by UA-cam is this: When you have those bullets loaded into a mag, give that mag a good whack on the backside at least 3 or 4 times before you slip it into the receiver. Specifically DO NOT GRIND any operational components 😛
Also I'm like Baz Luhrmann of "Sunscreen" fame. All of my advice is based on my own meandering experience. No education or training, unless you count a WWII navy vet teaching me (and then drilling me on) what he learned in Basic about H2H and firearms, starting when I was big enough to be able to lift his Remington .44 revolver.
