PMM Compensator for HK VP9

Compatibility with Heckler & Koch VP9A1 F

Compatibility

Modification required

Model
Heckler & Koch VP9A1 F
Based on
Manufacturer documented

Based on manufacturer documentation or support information.

Requires a THREADED BARREL in M13.5x1 LH (H&K factory barrels) OR 1/2x28 (SilencerCo barrels). Most of these pistols do not ship with one — check your barrel before buying. ⚠️ THE SINGLE BEST ARGUMENT AGAINST A THREAD-PITCH MODEL: PMM sells the same comp body in TWO different pitches for the SAME pistol — M13.5x1 LH sized to the H&K factory metric barrel, and 1/2x28 sized to a SilencerCo aftermarket barrel. The buyer chooses by BARREL, not by gun, so no single pitch can be attached to the host. Explicitly NOT compatible: VP9SK, VP9-L, VP9 Match, P30. Shim-and-timing mount, no set screws.

Check your exact model and part before ordering. Fitment limits
