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?

The tip of the firing pin strikes nothing, what happens to the
shoulders of the firing pin do they hit anything? The firing pin is
not just a rod it is a machined part.

Let me go and disassemble my M1911 and take out the firing pin and
look at it.


All that protrudes on my SIG is the pin that hits the primer. If there
is no round in the chamber, there is nothing for the pin to strike. It
wasn't an issue on the GLOCKs I've field stripped.

I have no familiarity with the "innards" of 1911s.

Just like you to see only what's on the surface and not worry about
what's underneath.
