Are you talking about cycling issues? That's not unique to the P320, just like with a compensater a suppressor can cause cycling issues with some ammo. I use a suppressor with an XCarry sometimes. If you get the Armory Craft spring tuning kit you won't have issues.

 

Just got my Silencerco set up and use the Armory Craft spring tuning kit for sure. Run some 147 grain to work every thing in.

 

To be perfectly fair, I would not even call it an 'issue'.
Tuning of the firearm is pretty much mandatory when a can or a comp are added.

IF your gun happens to cycle with a can or comp just fine, most likely you still do not have an ideal spring there.
The recoil spring that is in the gun from factory was not designed to work with a can or a comp.

PS:
Thank you to those of you who gave our P320 recoil tuning kits a try:

Thanks for the info. Will your compact model recoil kit work in the P320 XCompact? Your website says it won't work with the stock oem 3.6" barrel. I would use it with the longer Sig threaded barrel.

 

Did we ever find a way to fix this issue with the xcompact?

 

i run an p320 Xcompact as my edc, and i have a suppressor for it that cycles perfectly with 147 Federal HST, that i use as my Def ammo and my subsonic ammo with my can, to make it work perfect get the DPM recoil kit and with your order email them and ask them to add the softer springs with it, they will add 3 lighter springs to your order for free. and figure out which one your gun runs best with.

 

Also all Sigs should be broken in before you can expect them to run flawlessly, the barrel lock-up is too tight when they are new, give it 200 RDs than make your decision.
