Auto pistols.
I've had mostly 1911's,(6 Colts, a Detonics, a Springfield, and an Auto Ordnance parts gun) and several Smith autos. Never had one that worked as reliably as the Smith 29's and 19's Ive had. A couple of the Smith revolvers I've had for 24 and 30 some years, with never ever a failure to fire. Compared to that, an auto that fails maybe once every thousand or two thousand rounds doesnt seem worthwhile to trust to me.
Also never had or shot an auto that I could reliably hit running rabbits or squirrels, or things thrown in the air. Can't seem to shoot autos as accurately either (group size on paper).
Never had a failure with a Winchester 94 either(other than a broken firing pin from lots of dry fire when I was about 14). Had one problem with a Winchester 1886 that was about 100 years old. Bending the cartridge stop with a screwdriver fixed it. Had bolt guns fail to functon in several ways. Mauser and 1903 Springfields.
Had a couple of Ruger SA transfer bars break, but other than that, and a Super Blackhawk that had a weak base pin catch spring, never had a malfunction when shooting. Smith revolvers have been more reliable overall for me.
