If we're just talking shootability...
I love my Beretta 90-two .40 cal, even if it does have a plastic trigger (easily replacable, I'm told)
My Taurus PT1911 - ok, yes, I've heard all about (and experienced) their lousy customer service, but the pistol is built rather well (minus a shallow dovetail on the front of slide, which is being fixed and will post pics as soon as I have it back)
My favorite self-cocker was a 4 1/2" Colt King Cobra in .357 mag, stainless with black rubber grips...wish I'd never sold it, I miss it every day...
Last but not least, my Heritage Rough Rider SA .22 mag; my smallest caliber I own, because I needed a dependable plinker/varmit/coyote repellant while I was roaming the countryside of south central Texas
