    Good product, but not designed to accommodate manual safety

    When I received this product was well designed for P320 FCUs that do not have a manual safety, but with a manual safety, the FCU did not fit. Pins can still be pushed through, but FCU wobbled in place rather than fitting tightly in the armorer’s block.

    After contacting customer service, they had me send back the block and they milled it out to perfectly fit the FCU for my P320 M17 with a manual safety. It can accommodate the safety in either position and is now a perfect fit.

    Grayguns customer support was AMAZING in helping me get my issue resolved!
