That's why you need a backup. ;-)

To be fair, most service revolvers today (of the few remaining) have firing pin blocks and frame mounted firing pins. Until someone proves to me that dry firing a vintage S&W is totally fine, I will stick to the old wives' tales... Besides, you guys are supposed to practice dry firing. We have real jobs to do.

Some shotguns can be damaged by dry firing. The shoulder of the firing pin slams into the firing pin carrier. In time the firing pin will go through the front of the carrier. It takes a lot of dry firing for any damage to occur to a shotgun.

Well here is something I have noticed in a few centerfires that have had dry-firing. The tip of the firing pin is hardened and designed to a particular length to strike the primer. If you pull the firing pin out and you see it is a larger diameter than the portion that goes through the pins hole in the breach face, which will then typically be tapered or may even be squared off down to the portion extending beyond the hole. What can happen without something for it to strike against is the tapered or squared portion can slam against the inside of the hole which can cause the tip of the firing pin to snap off over time.

Shotguns are technically center-fire – just how much dry firing do you want to do? Do you just want to clear it or do you want to do a lot of practice shooting or what?

Don't dry fire a cap and ball revolver, unless you want messed up nipples. Who wants messed up nipples? Then it's too hard to seat percussion caps.

Just to clear it before I put it away, and I do that, dry fire it and put it back away about once or twice a week.

Yes.

This is a urban myth perpetuated by lack of understanding. Much like the myth of cowboys always carrying revolvers loaded 5 instead of six. Revolvers of the era had half cocks which acted as a modern firing pin safety. They would load all six cock it to the first click stick it in the holster.

While much like today foolish folks in the old days would sometimes carry 5 like foolish folks today carrying with empty chambers...

What broke firing pins off hammers were guns that were out of time and the pins would hit the edges of primers or cylinder walls.
