I carry a HK P2000 9mm in an Old Faithful hybrid iwb. It falls in the compact range, and still disappears wearing only shorts and a t-shirt. I'm 5'11" and 165 if that means anything.
All of the above....
Normally my pick is either my hi-power or Government frame 1911. When a little more decretion is required, I opt for the J-frame or my MK-9. If its more of a social situation where I want to dress it up a bit, I carry the officer frame 1911 (stainless with rosewood grips). 90% of the time its IWB carry, but when Im riding the bike, I tend to go for the vest carry or a shoulder rig.
