    Gun is great when not running a suppressor on it. I put the can on and I get failures in 3-5 rounds. I have sent it back to CZ once, they polished everything. The gun is still failing with the can.
    My only thought is to beef up the recoil spring. Any other suggestions?

    If the spring upgraded spring doesn’t fix it, I will probably sell it.

    I am currently upgrading my M&P 2.0 with apex threaded barrel, apex trigger, stronger recoil spring, and suppressor night sights.

    Failing how? Failing to eject or chamber a new round? If it's this, is seems like you have too much mass to cycle completely. Is the silencer attached to a booster? Maybe try a lighter recoil spring or a different booster spring.

    What can are you using?

    It seems to not be going into battery, or light strikes to the primer.
    I am using a rugged obsidian 9mm can. It has a booster. I can take it apart to ensure there is no binding or catches.
    Honestly, I believe there is too much mass for the gun. That is why I want to upgrade the recoil spring.

    I would recommend taking the piston assembly apart and making sure that there isn't heavy carbon build up in there, your o ring is still soft and putting a little lube on the moving parts. I just cleaned out my 9mm can after about 2k rounds and it required taking everything apart. Both the booster assembly and my three lug assembly were close to non-functional .

    Boretech c4 helped a ton with softening the carbon deposits.

    Also, make sure you're not using crap ammo. Freedom munitions 147 grain 9mm was too weak to cycle my Sig reliably, I've not had any issues with Federal or Speer.

    And, since you're in Houston, if you want to meet up at Shiloh over lunch one day Mon-Thur or ASC any weekday after 4:30, you can try my Ti-Rant on your CZ and/or your Obsidian on my Sig to see if that points to one or the other being an issue.

    I am running 3 different kinds of ammo through it. Browning 147 gr, Winchester 147, and I think Speer 147 gr. Same issue with all 3 brands.
    The can a newish, probably has less than 300 rounds through it.
    I can probably get to it this weekend and take it apart.

    I would love to take you up on the shooting offer. But I work a ton, and my wife hates being left alone with the kids. Hell, I may still take you up on the offer anyway.
    What is, and where is Shiloh?
    I am completely familiar with American Shooting Center. I have a 300 blk sbr I want zero and accuracy test any. ASC would be good for that.

    Shiloh is a small indoor range run by some awesome folks. It's close to willowbrook mall by 249 and 1960

    When I get some time off I may send a pm. I am just south of Bellaire inside the loop.
    I am looking forward to sorting this out.

    If anyone else has an idea please chime in. Thanks for your time.

    Does regular supersonic ammo cycle without fail? Maybe the suppressor is not uncoupling completely and therefore adding to reciprocating mass.
