Suppressors FTE with Compensator

[NY700]

So just playing around I installed a storm creek barrel and YHM compensator on my M&P 9mm. Not having enough compression to fully cycle the action i dropped the recoil spring all the way down to 12 lbs. have tried factory loads 115gr-147gr and handloads in the same range and all though better, its still not fully cycling and wont eject the spent round or the new round will jam half way. Do i simply need to run hotter rounds or will i be dangerously exceeding pressure thresh holds or is there some other mod to make. its a blast to shoot with the comp on it, about the same recoil and muzzle rise as my mark III .22 Here is a link to the comp im running. maybe just too many ports?

Re: FTE with Compensator

I had cycling issues with my Glock 17L with a Jager comp. I was running 124gt +p with a 13rd recoil spring. Called Jeger and they said go with an 11lb spring. That did the trick. Hot Ammo and a really light spring seems the way to go...
