an anon who understands right here. looks like a normal semi auto pistol with a suppressor which doesn't have a recoil spring meant for use with suppressors, so it didn't cycle properly. he clears the malfunctions quickly under pressure, so it seems like he's experienced with shooting, but either didn't have a chance to use his gun with the can on it beforehand, or didn't care and just decided to cycle it by hand. second one seems more likely to me since he didn't seem surprised at all that it didn't reload.
