I'm 6'4" and 250 lbs. Mostly muscle, but my age and the wife's condition, and therefore lack of gym time, are growing the "love handles" at an alarming rate. I gave up on the IWB long ago and adopted the OWB carry and started wearing my shirts out for the first time in over 30 years. It's something I should have done long ago. For me, it's Don Hume's JIT Slide for the Kimber UCDP and H&K USPC, an Uncle Mike's Kydex for the Glock 26, and the latest is a Galco M7X Matrix for the Glock 29. All of these are extremely comfortable, all but maybe the Kydex hold the weapon close to the body, (so you don't need that big shirt look) and in the case of the Galco and Kydex, offer very good retention. All are very inexpensive.
I always carry a P32 in a pocket holster for BUG.
