so i have a glock 17 with a crimson trace laser on it. I wasnt sure if i this gun would be idpa apporved with the laser on it. any help?

The crimson trace laser is not a problem as long as it is turned off for the match. Best bet would be to replace it with the standard glide rod for the match, or take batteries out. They will be more strict at a sanctioned match.

well mine wraps around the grip and the batteries are really really hard to get out so i might just use my glock 22. i was just trying to save a little on ammo. what time do the matches usually end?
