ZEV V2 PRO COMPENSATORThe ZEV V2 PRO Compensator was developed and optimized for use on the G19 but will fit and function on all Glock models with a corresponding threaded barrel. Due to its compact size, when installed on a G19 with ZEV threaded barrel, it has the same overall length as a G34 slide and is compatible with most G34 holsters. It features contoured porting, an enlarged guide rod channel, and a new mounting system which permits secure installation and removal.
