I would like to get into the sport. Is my Glock 23c .40SW okay to use. I wondered if the compensated barrel might be against the rules. If so, I have a noncomp barrel I could drop into it. Also, I'm anLEO. Can I use my hi-caps, or would I need to pick up some ten rounders? I need to go watch a match when they come to the range in my area; and see for myself.
