Admittedly I’m far from a high volume shooter but does anyone have first hand experience with suppressors beating up PS90s? I know scars can be shitty but the ps90...? *chopping factory barrel to 10.x” |

Extensive use of a suppressor can cause damage to the P90/PS90 in the area of the takedown button. One solution that has been discussed is to use a 9mm suppressor or a .30 cal one to reduce back pressure, Jay Wolf has been trying to come up with a repair, but the last I heard he hasn’t figured one out yet.

I’m currently trying to find a suppressor to handle both guns without causing damage. |

| Basically any high volume can with a larger than .22 bore. Someone posted on fnforum.net their PS90 SBR wan as quiet with a 9mm can as with a PS90 specific can! |

Supposedly you can crack the buttstock pad when there's excessive backpressure in the system from the can. Solution, shoot 5.56 or 5.56K cans and don't use anything faster than AE TMj/SS197SR. Preferably use subs :D Problem solved. Ktec really didn't think the muzzle end through on the P50. They didn't give us really any shoulder to use for shimming brakes. |

I used to use an official 5.7 suppressor on my PS90 SBR, but I could tell it was causing damage to the frame. It caused a large amount of blowback and even popped out the mags and even cracked one magazine. I decided to put a dead air muzzle brake keymo mount on it and use a Sandman K with an e-brake front cap. The Sandman K has very low backpressure and the e-brake attached to the end of the Sandman K releases gas at the end of the suppressor further reducing backpressure. It being a .30 caliber can helps even more with reducing backpressure. All of these combined has resulted in no more mag pops and almost no backpressure from the gas while still keeping it hearing safe. I highly recommend you use a .30 caliber can that is a "K" size to keep backpressure at an absolute minimum. Even that combination should keep the PS90 hearing safe and significantly increase its lifespan compared to any other suppressor combination. |

| I mean official as in specifically designed for the 5.7 caliber. It was made by gemtech. From what research I've done it appears 5.7 suppressors are made for the FN 5.7 handgun and they aren't actually meant for the P(S)90 because of the high pressure that can damage the frame. |

Even that combination should keep the PS90 hearing safe and significantly increase its lifespan compared to any other suppressor combination. This is very good to know. GSL still makes the P90 suppressor and brake (bi-lock) for the PS90/P90. Greg Latka (owner) was on the design team that made the Gemtech SP90 suppressor for the P90. If you watch the old FN video with Ben Voss demo'ing the P90 you can see the bi-lock brake. Same with the promotional brochures from FN during the mid-2000s. I still have mine from 2006 or 2007 and on the very front you can see the Gemtech/GSL P90 brake. Gemtech no longer provides any warranty coverage for their pre-2016/2017 cans after the S&W purchase. The GSL P90 brake weighs 120g (heaviest of the muzzle devices) and that bi-lock restricts you to Gemtech/GSL/CMMG bi-lock suppressors (they're all made by GSL). I guess I could try a YHM R9 with a Rearden muzzle device on the CMMG thread adapter. |
