Well, you’ve never heard MY harsh language obviously... be that as it may, a properly loaded and maintained c&b revolver should be close to 100% as reliable as your favorite cartridge revolver. If you’re picking caps out of the works there are modifications that will virtually eliminate this problem. A .44 round ball over 25 grains of 3fg is an absolutely deadly weapon out to 50 yards and more. The limitation is really the capacity of 5 rounds and there’s no way to reload under duress and while possibly under fire or in a hand to hand combat situation.
Yes, I know about the spare cylinder reloads but it’s not viable for the average shooter engaged with an assailant. Unless you’ve experienced the loss of most of your fine motor control due to the massive adrenaline dump you don’t understand how much of a problem that is... I’ve watched guys trying and failing to reload an M16 while under fire. Multiple tries and just couldn’t get the box into the receiver.
All that said, if you are limited to a c&b, for whatever reason, you would be advised to carry two of them for the fastest, easiest reload. Possibly practice sprinting away from trouble as well. As others have said, it’s better than a knife, or fists, teeth, and fingernails... practice situational awareness every day. It’s easier to win the fight you saw coming from far left of bang. Easiest of all if you see it coming from so far away that you’re not even there when it would have happened.
