Since the 70's I've owned and carried .357 magnum revolvers. Two words, Autos Jam.
I carry a 640 Pro Series with 3 speedloaders in my back pocket. 20 rounds total so I'm not outgunned ammo wise.
Any gun stops functioning if you have a squib, a piece breaks ot falls off, only semi automatics require the ammunition they fire to be within certain parameters to function.
At least in this way revolvers are more reliable.
BTW, one of my catastrophic revolver failures was with a Model 60. While the problem was diagnosed as bullet jump preventing the gun's cylinder from turning, it took an eternity for our armorer to very carefully re-seat the bullet thus allowing the cylinder to open. Regardless of cause, it was a catastrophic failure, which means I'd of been out of a fight were a bad guy putting rounds on me.
I survived three deadly force encounters armed w/my issued thirty-eight and handling it is just second nature, while the auto loader is not as natural for me.
