I carry a Taurus PT1140 as a conceal carry during the summer and a Glock Model 22, .40 Caliber during the cooler seasons (Jackets and shoulder holster or side holster) and transfer my Taurus to the back-up position.
You want to play ganes carrying anything less than a .40 caliber, then write your obituary now so it looks good and sounds cool in the newspaper.
A .40 caliber will stop even the worst of intentions. I couldn’t agree more.
