Congrats, you're going to love this pistol.
Grumpy1 gave you all you need to know, curiously with none of my VP9s, I had no issues from NIB (after clean/lube with MPro7) with 115 Blazer Brass or other 'weak' (aka cheap) new brass ammo...I don't shoot reloads nor anything but brass.
Others have said the new spring requires some break in with hotter ammo, so Lawman, Q4318 Winchester NATO, MEN NATO, or maybe even Fiocchi which is generally a bit hotter than standard....Fed American Eagle works too.
Easiest gun to shoot all day long, I've gone through 500 rounds in couple hours at range (no cleaning required) and could have kept going except I ran out of ammo.
