Steyr S9 around the house and when wearing an "overshirt." It fits in the pocket of cargo pants, but needs something to cover the pocket. Without a cover garment it's a Makarov (East German- very nice gun, especially for $110). BUG is a .38 snubbie. Sometimes it's 2 .38s. A S&W tacticool folder completes the ensemble. I have found that a gun isn't much good for field dressing an apple, removing a hangnail, or eating a pork chop.
I have a small.45 auto, but 9mm ammo is SO much cheaper and the Steyr has been completely reliable with every weight bullet available in 9X19mm. The Mak has also been perfect in reliability, but marginal in power if you're dealing with a meth head who may or may not even realize that he's been shot. The 9X19 got a reputation as a poor stopper with military ball ammo, but with modern JHP there isn't a lot of difference in the relative stopping power of the pistol calibers from 9mmP through .45acp. The 9mm is cheap enough to practice with and shot placement trumps caliber. A hit with anything beats a miss with anything, and the fact that he always works with any ammo I have used makes Mr. Steyr my choice for bad breath range social encounters.
