Never had a problem with them in my SAM 1911 9mm.
They ran perfect in my SAM 1911 until the lacquer jammed the 40th round in the barrel .
Had to use a aluminum filler rod to drive it out.
I think for the price I will just give them away to the first person at the range that can use them.
I grabbed a box of them also to try in my new to me CZ 75b. They also have brazier brass 124 grain for only $2.00 more
