Mini-14 ..... another broken firing pin

Another broken firing pin today on the Mini-14. Last one was 6 years ago.

Is that normal ?? A design flaw ?? Or just my bad luck ??

-- Six years ago (when the original-issue firing pin broke) I did the install myself. I was not aware of any "fitting" requirements.
-- No increased-weight-hammer-spring installed, everything is original.

Ruger says they need to be installed by a gunsmith... not sure what the specs are and so the time mine broke I let a local guy do it.... may also have to do with the primers on the ammo you are using. Seems a lot of that foreign 'commie' stuff has hard primers.

Today Is Firing Pin Install Day.

In today's mail I received the new firing pin.

re. "Fitting" the new firing pin.
I found this statement elsewhere on the internet: "There has to be few thousands gap between tang and bolt when pin is fully seated in firing position so that pin is stopped by bevel on pin against inside of bolt and not stopped by tang hitting bolt when struck by hammer."

My Question: what is the "tang" on the firing pin ?? Near as I can figure from reading elsewhere: the tang is the back-end of the firing pin which is struck by the hammer. I just want to verify that.

Other than that, I'm reasonably certain I understand the rest of that statement.

Thanks Much for your sharing your knowledge.
