Earlier today I was using a 9mm usp tactical with octane 45. Overall, No issues with 115 supersonic but with 147 gr ammo (900 fps) the gun would not cycle properly either with our w/o can. The subsonic ammo didn't not have enough juice to rack the slide back and load a new round into the chamber. The spent brass would get caught in the slide along with the next round going into the chamber. Very frustrating.
This same subsonic round (147 gr w/ 4.5 gr of power pistol) works fine in other guns with and w/o can.
I am thinking the serious double recoil spring system in the usp tactical is likely the culprit.
Can someone recommend what subsonic load works in usp tactical 9mm with and w/o can? Thanks.
