Just fine in anything I've ever used it in... and reasonably accurate. That's one subjective opinion though... so wait awhile, I'm sure someone will have had issues with it.
I have used several cases of it in 9 mm. Works fine for the range. It is good plinking ammo. The primers are on the hard side if you shoot a pistol with a lighter then stock hammer spring. I have one .45 that doesn't care for them. The case doesn't expand fast enough and occasionally some unburned powder gets on my forarm. It still works when it does that. You can't really reload them. The cases will work for making nice dummy rounds.
Works in all my guns,semi or not,.380,9mm,45acp,38spl.
Who ever says it does'nt or leaves aluminum flakes in their
guns are full of it or little Nancy complainers or their weapons
are the issue lol
Agree with the other two posters about the CZ. One of the CZ-75Bs I used to own would stovepipe when fired with Blazer ammo. Otherwise, it seems fine in other pistols.
