Magpump Magazine Retainer Features The Magpump magazine retainer is molded from polymer specifically to fit the Walther P99Q magazine holding it steady while a Magpump 9mm speed loader is used to charge the magazine quickly. Designed as a companion piece to the Magpump loader system the retainer eliminates the awkward hand positioning often needed when loading a magazine by hand or with a generic loading tool. Its dedicated fit for the P99Q means it seats and functions exactly as intended without needing to be forced or adjusted. For Walther P99Q owners who already use or plan to use a Magpump 9mm loader this retainer speeds up range prep and reduces thumb fatigue during high volume loading sessions. It is a small inexpensive accessory that meaningfully improves the reloading workflow for that specific pistol and loader combination. This Magpump magazine retainer is available for sale at GrabAGun for shooters looking to streamline their range day setup.
