Mike, As a pistol with short barrel and gas tube standard ammunition will work just fine. Can experiment with subsonic ammunition. Will be a little iffy.

It should work fine with both however all pistols are different and it may be picky with some subsonic rounds

Mike, this pistol has a Pistol Length Gas Tube and should cycle Super and most Subsonic rounds. You can confirm this with Bravo Company USA at Toll Free 1-877-BRAVO-CO (1-877-272-8626) - Mon - Fri 8am - 4pm CST.
