And your question is??? Which ones maybe? Call Greg at Glock Meister and he'll fix you up with a set of Meprolight adjustables. Put some on my G20 they are fantastic, and well made. I don't even have a problem carrying the gun with them, but i use a galco half harness shoulder strap with a jackass hoster, that set up will hide anything under even the thinest shirt and you never know you got it on.
