Magwells for FN 545

A magwell widens the magazine well opening and chamfers the entry point, making the incoming reload more forgiving. The FN 545 is the .45 ACP variant of the FN platform -- its magazine is wider than the 509 and uses different lower frame dimensions. Magwells for the 545 are specific to the .45 ACP configuration. A compatible base pad closes the funnel at the bottom. Confirm on the individual product page before ordering.
