Use a snap cap when practicing.

I wonder what you guys think the business end of a firing pin hits when
there is no round in the chamber of most centerfire semi-autos?

I know what it hits in my SIG when there is no round chambered.

Nothing.

:)

I'll leave it to the gun geniuses in here to figure out why.



It is not a repeated over and over movement. Bigger problem is the hammer
incorporating the firing pin.




Oh, really? Gee, on my SIG the hammer doesn't "incorporate" anything
except itself. It kinda sticks "out there" on the back of the pistol. It
is a lever. Now, a lot of semi-autos don't have external hammers. GLOCKs
don't.

Here's an animation of a more simplified process. If there is no round
in the chamber, the firing pin strikes...nothing. If it strikes nothing,
it is unlikely to "break" during a dry fire.

Here's an animation of a GLOCK:

You can see that if there is no round in the GLOCK, the firing pin
strikes...nothing.


Next?

Is there some reason to dry fire your Sig? While on the telephone? Does it
make you a better in-home shooter?
