(Just love the word "autoloader" ...)
Of the various things I got to try at Shootmoot, I liked the revolvers. Simpler, I guess. Granted, they don't hold as much ammo, but even so...
Though the .22 rifle was wayyyyy too much fun.
A revolver should always be the first centerfire handgun in your inventory. It's 100% foolproof and panic-proof, at least as long as there is ammo in it.
I seriesly recommend the S&W Model 640, a five-shot stainless in 9mm. Plan on searching for perfect grips for your hand, because the grip is tiny, and you want total confidence in your handling of the weapon.
