Anyone here shoot a .45 Super? Same size case as the ACP but thicker brass.

The case hangs on the extractor, as do most all 45acp cases.


Yep. This is why case length isn't as critical as many think. How many of you actually check to see if your acp and parabellum cases are actually headspacing on the chamber or actually not quite? Of course - if you have push-feed issues, that longer headspacing may allow a misfire.

Lunatic fringe....we all know you're out there.
