Suppose my carry for the day will depend on my mood, clothing, weather, where Im going and what I will be doing...
I like a choice.
Generally it will be the SW1911 Pro Series .45ACP either in a pocket holster or Galco Avenger on the belt...or the SW 340PD Air Lite .357 magnum in a pocket holster..One of those two will go with me about 90% of the time...On a few occasions I will tote the Sig P220 .45ACP or the Sig P239 in .40SW...I consider my Sig P238 in .380ACP every once in a blue moon...380ACP is somewhat puney for a serious social engagement...Something some like to carry to make themselves feel better.....I try to tell folks to get the largest caliber carry weapon they can handle and conceal, because if it ever happens they must use it in a real gunfight, they will wish whatever it is their fist is wrapped around is bigger, more powerful and has more bullets!!! But even a .380 or less beats a cell phone.
Dont feel the need for a backup these days, for most occcasions, but in my LEO days I generally carried 2. I do believe in at least one extra magazine for autos and extra rounds for the wheelgun kinda mandatory. Althought I dont plan taking on Al-Quada, even in a single thug engagement, that first mag or cylinder is most likely going to go fast. Better hope buisness is taken care of by then or pick up a big rock and get back in the fight.
