How many of you use thumb breaks on your CCW rigs? My main carry weapon is an XD40sc; it rides in a desantis pro stealth holster w/ thumb break. when I practice drawing, i'm much slower with the break than without it. Problem is, I worry about leaning over and my gun falling out of its holster when im out and about. Anyone have any similar issues and/or solutions they can share? Or recommend a better IWB holster?
