I own and CC a Glock 19, in a Crossbreed Supertuck IWB holster. Couldn't be happier. I often forget I'm wearing my gun after its been there for a few hours. I'm a big guy, 6'1" around 280 and have no problem consealing a 4" Glock. I've got over 1000 rounds through the gun, and never once has it FTF/FTE. If you want something smaller in 9mm check out the Glock 26, highly recommended.
