If I really had to pick just one it would probably be none of the above. It would be a single stack 9mm like a Ruger LC9. I am smitten with my revolvers but my G26 has been gaining ground.
Anyone remember the movie "The Gambler" with Kenny Rogers. When confronted by four guys with knives Brady Hawkes (Rogers) pulls out his derringer. One of the bad guys remarks that Hawkes only has two bullets and there are four of them. Hawkes replies, "The question is... which two of you are willing to take the bullets? So the other two can do the cutting."
Guess that's why mechanics have lots of tools. My J frame, in pocket carry, gets the most work. In jacket weather a 3" model 66 in .357 goes on the belt. Weddings, and 'suit' occasion gets a J frame in a ankle holster. Truck has a 12 gauge, with folding stock, or a AK folder. Right tool for the right job.
