It could be related to the short bullet but try a few different magazines and see if they all do the same thing. Sometimes jams are related to one bad mag in a bunch.
Feeding issues are related to bad ammo or bad mags usually...but customer brought in a pistol that wouldn't feed factory ammo, it wss a Beretta or Tanfoglio.
The reason it wouldn't feed wasn't an ammo or mag issue. I found the real problem...
The barrel didn't have a chamber!
Whoops...
Apparently they just slap them together and ship them out...they obviously don't test fire them at the factory.
