I've been looking for a Crossbreed style holster that has a kydex clamshell (kydex on both sides of gun, but leather against body) so that it won't push the mag release when wearing all day. I've drilled a hole through the leather on my crossbreed where the mag release is which has solved the problem 95%, but here in Texas sweat gets on mag release and rusts it. What's out there that I can't seem to find?
