This is hands down the best stock duty pistol that I have ever shot. I'm a hardcore glock guy and the VP9 blows me away. As a lefty, I have a slight problem of riding the slide release, but that's on me since I've never been able to use one on a glock obviously.
Despite the mag release being new to me, I've had no problem hitting it at the range or at USPSA. I was personally unimpressed with the triji HDs for this gun (they'll be up on the HESM soon) and I plan to buy a second to have it milled for an RDS. Based upon the bullseye scores I was shooting at 25m with the crappy stock sights, I expect this gun to easily group at 50m+.
Now that 3gn has changed their rules and has a 15rd mag cap, I'll be using the vp9 in the factory division this season and I'll shoot it at the NRA TPC matches if I can find an x300 retention duty holster.
