It's the only IWB position that works for me but I have a fairly big belly and always wear untucked overhanging shirts. For me, it feels like the safest position 'cause it's right in front so it's easy to protect and natural and quick to pull up on. It's comfortable enough 'cause all my carry guns have 3.5" or shorter barrels with compact grips... Smallest being LCP, biggest being SR40c.
What did Mrs. Bullet say to Mr. Bullet? ... "We're having a BeeBee!"...
IF THE SHOE FITS, WEAR IT!... IF THE GUN FITS, SHOOT IT!
