    My photo-taking skills may make this query unanswerable, but...

    if you can make them out, what do these examples indicate?

    I bought a couple thousand pieces of once-fired police range brass a year or so ago. A majority of the caseheads I have looked at have firing pin hits like these.

    While I'm at it - most of the cases are head stamped 'Speer'. many of them have a small number 13 at the 9 o'clock position...?

    Those are the experimental fire pin ID marks made for identifying the gun that shot the bullet.

    Aha. Some of the marks are, ah, disruptive to the metal of the primer. I wonder if they got any blowbacks during their experiments.

    To me, and this is just to me the difference seems to be in stryker fired pistols. I noticed those strike marks when I shot a Glock vs my SR1911 Rugers. I picked up some .45 cal brass this week end and it had similar marks but the guy next to me was shooting a stryker fired pistol. I could be wrong tho.

    Glocks use rectangular firing pins. Most LEOs carry Glock 40s.

    I had a question on another forum about some 40 s&w's. I was told they were fired by a Glock. This info was given based on the firing pin indent that looked exactly like those. I'd say they were fired from a Glock. Just an uneducated guess.

    I agree. Those look like a clock firing pin mark. Have a few glocks. That's what the firing pin primer mark looks like.
