I found a decent price on a 9mm P320 and wondered if anyone has found any ammo brands it doesn't like and can you tell me if it is +P rated. I think my P238 would shoot rocks if you could load them. It seems to like everything I feed it.

Your new P320 will shoot whatever you feed it. Try a few different kinds and see if one gives you better accuracy.

Not sure about the +P issue.

Mine has fired the traditional 9mm weights fine- 115, 124 and 147. These include handloads and factory ammo. Some have been +p 124 grain Gold Dots as well as some Federal Hydra shock.

The general consensus on +p is that it will increase wear due to the increased slide velocity and pressure. I believe the manual addresses this but I couldn't find it if I tried. It will fire +P. I wouldn't hesitate to fire several hundred or more in mine.

I've fired a wide variety thru mine in a short period of time. It's handled everything, including my sometimes crappy reloads.

Mine likes everything I throw at it.

+P is SAMMI spec and is fine in a P320. +P+ is a no.

Broke down and bought the 320 today. Can't wait to get it on the range next week.

+p is fine, but it will accelerate wear to some degree.

No manufacturer will ever approve +p+ because it isn't a Sammi spec and has no defined upper limit. Approving its use would put a manufacturer in jeapordy with regards to liability should someone blow themselves up with a ridiculous overcharge. I've sent some 9bple down range through mine with no signs of a problem. If I was going to shoot it often I'd make sure to stay on top of recoil spring changes and expect to see early wear.

Honestly though, with today's projectiles +p really isn't needed. 147 gr HST and Gold Dot, and even the 124 gr standard HST load, performs nearly perfectly when tested through denim and into gel.

I've yet to shoot anything through my 320 that it wouldn't feed, either with the full sized or compact upper. I've become a big fan of the pistol.

 
Mine is strictly for the games, so I shoot my standard 9mm load of 147 FMJRN Precision Delta bullets over 3.9 gr WSF, which makes minor power factor with plenty to spare. My overriding philosophy for the games in any caliber has been to go with FMJ RN bullets. You don't want feeding problems on the clock.
