Yeah I'm 5'10" 225lbs (I'm big boned, not fat...that's what my mama says) and I appendix carry a Glock 19 or 3 o'clock a Glock 43. My belly shelf adds to the concealment. FUnny thing is the Glock 19 AIWB conceals better than the G-43. Holsters , position and belt really are key to good concealment. I still need to lose 35 pounds...then I'll be able to conceal an AR 15!
