Matches and good classes are really the best place to test out your gun. Once you’ve established that a pistol is reliable enough for a match or a class, take it to an actual event and shoot it at speed. You’ll learn stuff about the gun that can’t be revealed in dry fire or single lane training. As an example, in this USPSA video featuring the VP9 is that at speed, even with a solid grip, the gun tends to have a lot of muzzle flip. It’s nothing that can’t be controlled, but at the same time it was a lot more bounce than I expected from a 9mm. It actually flips the muzzle more than my .45 ACP 1911, which is odd.
So take your guns to a class or a match. You might be surprised what it tells you.
