The Shield Arms Premium Magwell for Glock 43X and 48 is a CNC-machined aluminum magazine funnel that speeds up reloads while keeping the slim shape of the pistol (Shield Arms part no. G43X48-MAGWELL-PRM-BLK). It is machined from solid 6061-T6 aluminum billet and creates an enlarged funnel opening that guides the magazine into the grip. The low-profile design adds little width, so the pistol stays comfortable for carry. It works with Shield Arms S15 magazines, factory Glock magazines and magazine extensions. It is made in the USA with a lifetime warranty.
