My standard EDC is an LCP in a pocket holster. For just a trench sight, sure is amazing how easy it is to keep it in a pie plate at 15 yards.
If I feel the need for something a bit more serious, usually my EMP 9mm or Kimber Compact CDP II. Although, my SP-101 in .357 with a 2 finger boot grip does make the random appearance.
Just too darn hot down here for the cover garments necessary for a major caliber firearm, especially since I try to avoid OC.
