I ordered leather pancake thumb brake holsters for my EDC 640 pro and my cw45(never carried due to lack of holster) a few days back. I have had limited experience with holsters, but the old school thumb brake that came with my Trooper mk.III is the only carry holster I own that I am 100% happy with. (Picked up yet another Fobus for my p32 too, but that's a different discussion.)
I always wear big untucked shirts, so OWB works for me. Speed of draw is nowhere near important to me as retention and comfort. I would have gone Safariland thumb release if that was an option, but it wasn't. (I imagine I will be getting one for my px4 in the future, and heck, my pt92 if a m92 version would work . Thanks to the guys at Bullzeye Sports in Wilmington, NC for letting me try their personal models.)
I guess I will be seeing the cons soon enough. Any thoughts?
