I have never fired a Glock or Beretta FA, but I have fired the Mauser Schnellfeuer and the Spanish Astra copy, and the Spanish Star FA pistol, as well as a Colt .45 converted to work like the Star. None were worth much, for the reasons given, even with the shoulder stocks on the "broomhandles". Another problem with an FA conventional pistol is that the magazine empties rather quickly, like brrrp! The Mauser and Astra, with 20 round mags, were a bit better.
