Ah blow forward - slam fire shotty! i used to make those (basically cock the gun by pushing the barrel forward, either manually put the bullet in or if ya made the gun good it can pick it up from the magazine, when it slams back) a spring would be on the outside of the barrel, pushing it backwards, a trigger mechanism made from one piece of sheet metal would prevent the barrel from slamming back (unless the rigger is pressed). This kind of weapon is really compact and easy to make, however has huge recoil (and no recoil dampeners, unless ya make a stock that does it) since the entire barrell slams backwards + the recoil from firing!
Making automatic or semi-automatic weapons theat use blow-forward (slamfire type) is easy too however the seamless steel pipes i used would wear out quickly (mostly from heat more than friction or propelalnts) and having a good seal between the bullet and barrel is far more important than in blow back weapons, and even a slight error (just like with open bolt old smgs from WW) could cause the bullet to be fired before its chambered (or at least chambered enough) which depending on the bullet can cause anything from finger/hand loss and shrapnel to just being singed and temporarily deafened (or if yer like me to use custom made weak bullets first, just shaken up that ya made a misscalculation, but awoided any damage to the gun and body)
I would also like to add that pneumatic gun should also have a pump atachment (so we dont need to waste canisters, and we can refill the propelant even while adventuring on planets for example) just like the RL things (which ya can make from PVC pipes almost completely, and fire marbles as lethal velocities)
