I have rented the vp9 at the range and I will eventually have one...although first I'll probably pursue the P30.
I love the ergonomics. It's definitely a striker fired pistol(vp9)no doubt. The trigger will need some breaking in but that's part of the fun. It's just easy to see the quality that goes into it (for a polymer semi auto pistol)
The VP9 is my only striker-fired pistol. Unbelievably accurate.
I pulled it out the other day after not shooting it in a few months, first round was dead center bullseye at 15 yards. I know that is no big deal, but it was surprising nonetheless. I had just changed the trigger spring, and did not install it correctly, so the trigger did not reset on its own (I had to pull it back out to reset it.) That was my only shot of the day needless to say! But what a shot!
Now that it is running properly with the spring installed correctly, I need to get it back out again and see what it can do.
