I shoot with a Sig P220 .45 and have for about 1 year. It is not the gun to play the game with if you are into the GAME but it is what I carry. I stay in the 50% or above in the rankings. On some stages were the lack or rounds (8) and combat sights doesnt matter I shoot way up in the standings. I am getting better every match and it is a blast.
If I was going to purchase a gun it would be a STI
But it would mean a change to .40 and I am not ready for that. to spend the money or the time to set up eveything
I can tell you the guys that win my clubs matches are world class and the top 3 all shoot 38 super cal .
