Requires a THREADED BARREL in 1/2 x 28. Most of these pistols do not ship with one — check your barrel before buying. YOU BUY BY BARREL, NOT BY SLIDE — the same shape as the VP9 two-pitch case, one level down. PMM sells two mutually exclusive options, "Factory Threaded Barrel" and "Aftermarket Barrels", and they differ physically: the aftermarket body adds approximately 1" to overall length, the factory body approximately 1.25". The SLIDE is irrelevant — "These comps fit both the 1.0 & 2.0 slides." Aftermarket barrels tested: Faxon, SilencerCo, Ed Brown, Griffin Armament. One part record covers both options because PMM sells them under one product; a buyer must still pick the right one.
