Crown
If your thinking about USPSA, you should be focused on shooting skills not bumping the gun. I have found after shooting both disciplines extensively, that USPSA brings you into a different universe of shooting, I was king of the hill for a little while in IDPA, then transitioned to USPSA, where I am an also ran, and I am twice as fast and accurate as I used to be. You wont damage your crown dry firing, which I recommend alot of.
Mainly humor, but the skill commentary is all fact, they just play the game at higher level in USPSA, may not be as tactically correct, but if your shooting at club with even a half commitment to serious USPSA, you'll see what I mean, Dan is building me an M&P now, can't say I'll ever jump from my beloved CZ, but cant wait to get my Dan&P full size 9 and play with it, that Canyon Creek XD, that I cant shoot to save my life.
