Just a reminder,,into the waaay back machine,
.
When in the Corps, we did the transition from the 1911A1 to the M9 Beretta,M92.
Well we had a few slides fly off,cracked frames. Hands scarred and even a few teeth extracted via flying slides.

All later was due to the fact the Corps got a great deal on IMI TZZ ammo.
Made for Uzis,kinda hot for those M9s.
