I got my first VP9 and am coming from a P2000. I bought this VP9 used, never fired, and had been sitting in a safe for a year. I put 500 rounds through it today without a flaw. However, one thing I notice that's quite different from the P2000, is that the slide is quite easy to pull back about the first 1/4 of an inch before it gets very stiff. I notice this as I'm wiping it down with a rag, I can feel the slide coming back a bit. My P2000 doesn't do this at all, it's stiff from the beginning. Now I did notice that the VP9 is very stiff to pull if the trigger is pulled and decocked. While cocked, is it normal for the VP9 slide to easily pull for the first 1/4 inch?

My 2015 VP9 failed to go into battery completely a few times over the first couple hundred rounds. I can believe the stories about HK upgrading the RSA to the VP40 in recent guns. Shoots ok now though.

Yea, it's normal.. I belive that's the reason new vp9s have a vp40 recoil spring. Even though it doesn't affect function some people were getting sketchy about it. I like mine and it does the same thing than yours.. please correct me if I'm wrong about the .40 recoil spring.

That's it exactly ! Very good. There are a lot of members here on this forum that have been around awhile that don't have a clue when asked that question.

Mine had this 'issue', it was last year production before they started using .40 cal recoil spring (mine was painted red). It was very unnerving, just seems that a pistol should strongly resist being forced out of battery to my thinking. This makes me much more of a P30SK fan over the VP9 as it is darned near standoff ready (meaning it can be forced out of battery by pressing the nose of the pistol into something).

Yep, mine did too until I replaced the original recoil spring with a VP40 spring. Now it's much stiffer and still functions great, even with range ammo. I'm pretty sure that all VP9s come with the stronger spring now.

Thank you guys. I will replace the recoil spring with the newer VP40 for the heck of it. I just don't like how easily the slide comes back when I'm doing something as simple as wiping it down with a rag. It made me wonder, will the slide come back some as it experiences resistance going into a leather holster? I tend to think it might, so I would like it to have more resistance.

I switched to a stainless guide rod and flat spring. Not a huge difference but I feel like the added weight in the front helps manage barrel flip.

Mine does that, hasn't created any problems. It's to be expected with the striker cocked, only has one of the two springs acting on it to keep the slide forward. If you're really worried about standoff, someone posted a video of a glock being fired with the shooting hand thumb behind the slide to no ill effect (other than obviously you have to manually rack it for the next shot).

I see that it is a striker fire issue. When decocked, it has all of the resistance I would expect. However, my mom's glock is still not so easy to rack when cocked.

That is because HK striker spring is very strong, to provide "hammer like" hit on primer plus Glock striker spring (unlike VP9) is not fully compressed when cocked.

This. Especially the second part. The striker spring opposes the recoil spring when the striker is cocked. I personally think it's bad design for the sake of a marginally better trigger. I can shake the pistol hard enough to drop it out of battery when using the old 9mm recoil spring. It is also one of the reasons the pistol is more sensitive to mud (though practically that's a non issue). It's one of my many complaints about the VP9.

HK offered to send me the "new" spring (VP40 spring for the VP9) but my VP9 has been flawless and easy for my wife to rack so I don't see a reason to make the swap. There's no mud in my home so I'm not worried about it going out of battery.

Mine does it too, but hasn't given me a single issue since 2014. I'm going to keep it as is, until it's time to replace the spring. Then I'll drop in the one for the VP40.
