I've always used dummy cartridges specifically made for dry firing for my single action and double action revolvers. It's always been my understanding that is required to eliminate firing pin problems.

But I'm told that this is not necessary for the semi-auto pistols. Before I blindly follow along, would appreciate some info on this issue.

Dry firing revolvers with transfer bars will not harm the firing pin.
Striker style semi autos like Glocks also will not harm the firing pin.
1911’s can be safely dry fired.

Basically any old style revolver that has the pin attached to the hammer or any striker style pin with out a return spring. Do not dry fire these with out snap caps.

I think the instruction manuals for my Rugers say that it is OK to dry fire.

Can't speak for others, though.

Snap caps would seem to be a good idea, in any case.

Dry firing is one of the few ways to gain proficiency with a handgun. I guess the bottom line is first check out your guns manual. If it does not say stick a snap cap in it. For sure with any rimfire.

I would use a dummy cartridge designed for dry firing like Snap Caps, because even with a fully floating firing pin you would have the firing pin would go forward and with no primer to cushin to blow hollow out the bolt face hole and make it larger or pinne it-self into the bolt face causing firing pin problem. Also firing pin spring problems. This would would protect the pistol and functionality.
