    Fit my slide perfectly. Ran 90+ rounds on first range trip with no malfunctions.

    Completion Kit - not so good

    The extractor, plunger, and spring set did not function properly in the slide. I replaced those parts with OEM Glock and it functioned fine.

    This was used to complete a Lone Wolf G21 Slide. Everything worked as needed. Would buy again
