Everybody seems to be talking about semi-auto's. If you're really concerned you could carry a revolver with the hammer down on an empty chamber. Still could fire with one pull of the trigger vs. awkwardness of racking the slide on a semi-auto. Modern revolvers have firing pin blocking bars and floating pins, just like the semi-autos. Personally I trust these mechanisms on chambered revolvers and SA's. But if you're really worried, carry a revolver on an empty chamber. You'll have 4-5 shots at best, but you may get that critical first one off faster.

When I first started to carry concealed, my opinion was that if the average CHL needed more than the 5-6 shots in a revolver, he was either going to be dead, or should have had a rifle (with a 30rd mag). Now I usually carry a 92F or SIG P226 with 15+1. I have no problem carrying a modern semi-auto chambered with hammer down.

I was in the Navy in late '80's-early 90's. The "officer of the deck" usually had an empty .45 1911 Colt holstered with one mag (with 3 rounds) in a pouch. Idiotic if you ask me. I guess you could beat the drunk charging up the brow ("gangplank") with the .45. Then again, the Navy was never the leader in small arms tactics (except maybe the SEALS). When Saddam invaded Kuwait in '91, I was courageously defending my destroyer in Norfolk, VA from the hoards of union and non-union shipyard workers "fixing" it. They decided to give us a flak jacket, helmet and M-14 with selector welded to semi. Mag w/ 3 rounds in a pouch. This was better because I could beat the crack dealers better with an M-14.
