Tough One
That is a tough one, I have been looking for that a # of years. lol
Still looking lol
Well, to the point.
I think it really depends what type and size handgun you are carrying and how the holster handgun combo fits your body and of course your dress.
For casual t-shirt type dress I usually use a iwb or a pancake and conceal a Beretta 92 without any real problems.
I like ted blocker and several others.
I just got a galco cop 3 slot pancake today and will try that one out and see how it works.
I prefer a thumbreak, I don;t find it takes much longer to access, but it sure makes me feel more secure.
Ya will probably be like most of us and have a few in a box somewhere that just didn't quite work out, before ya find the right one, then ya may keep looking.
I hope ya find it.
