I wouldn't swear to it but I think that the 1911 Pit Bull is an FMJ/hard ball only pistol seems like I read about one in AR some years ago the "hard ballers" don't like SWC or large cavity HPs . Can't remember 100%.tons of choices as a 1911 has about as many drop-in after market choises as 74'chevy.
Can't tell you a thing about your Luger .
Get them checked out and go try 'em out.
