So a question for those of you with pistol cans. Im running a xdm .45 4.5" with a barsto extended/threaded barrel with a gemtech blackside 45 can. the gun gun runs flawless unsupressed but with the can its runs pretty poorly. sometimes it wont pick up a new round after cycling and I have to rerack, sometimes it locks back with rounds in the mag still, and occasionally it halfway picks up a new round and smashes the round back into the case causing me to clear it. all in all just doesn't run very good. rarely I can get through a full mag without issue. my understanding is that with a can my backpressure should increase so i would think that it wouldn't short stroke the cycle of the action. my gun has aprx 6K rounds through it and i just ordered new recoil and mag springs to see if there just worn out and not feeding/cycling properly. this happens with various ammo types as well. any ideas would be appreciated.
