FPM Gunworks FPM Nein Features The FPM Gunworks FPM Nein is fully welded from 17-4 stainless steel giving it a tough maintenance-free construction built to handle repeated use on 9mm carbines and pistols. Its 7 inch length and 1.60 inch diameter strike a balance between sound reduction and a manageable non-intrusive profile on a host firearm. A direct thread 1/2x28 adapter is included so the suppressor can be mounted straight to a threaded barrel without any additional hardware. The internal 1 3/8x24 threading accepts quick attach mounts and works with booster devices built to that same thread pitch giving the shooter flexibility in how the can is configured. Offered in both 17-4 stainless steel and titanium the steel version reviewed here comes in at 10.5 ounces a reasonable weight for a fully welded stainless can of this size. The Black finish is durable and low maintenance holding up to the wear that comes with regular range and duty use. Because it is fully welded rather than user-serviceable the FPM Nein is built for straightforward reliability rather than disassembly which suits shooters who want a set-and-forget suppressor. The FPM Gunworks FPM Nein is for sale at GrabAGun for 9mm carbine and pistol shooters who want a rugged quick-attach-compatible suppressor.
