Just wanted to give you guy's a head's up. The HK VP9 is now being assembled with the VP40 recoil spring. You can tell which spring you have by its color: red spring = original 9mm spring, silver/normal spring = .40S&W spring. I just bought a new grey HK VP9. I shot it right away without cleaning it first (normally, I don't do that) and used 115 grain reloads I bought online. I put 100 rounds through it and had multiple FTFs and FTEs - it jammed about once every 5 rounds. When I got home I did a little research and found out about the new recoil springs. Members from other forums stated storing the firearm with the slide lock back and racking the slide multiple times at home helps break it in a little bit. It was also highly suggested to break it in with 124 grain NATO and 147 grain ammo.
I cleaned my firearm after its first range visit and returned to the range today. I put 25 rounds of Hornady 124 grain +p XTP through it without any issues. The gun performed flawlessly with that ammo. I then put 50 rounds of Winchester white box 147 grain HPs through it. It fired all 50 rounds without any failures. I then shot 25 rounds of the 115 grain reloads I bought online. I had 3-4 FTF and FTEs using that ammo, but it wasn't as bad as my first range trip. I ordered 500 rounds of Winchester 124 NATO to keep breaking in the pistol. I just wanted to give you guy's a heads up in case you run into the same problem.
Also, when I do start carrying the pistol, I plan on carrying Hornady Critical Duty 135 grain +P. Of course I will run a box of that stuff through it for testing prior to carrying.
