The Taran Tactical Innovations Firepower +4 Base Pad (brand part no. GBP45-01) is a magazine extension built for Glock 21 and Glock 41 pistols chambered in .45 ACP. Machined from billet aluminum and hard-anodized for a durable, long-lasting finish, it adds four extra rounds of capacity to a factory magazine without changing how the gun feels in the hand. TTI designed the Firepower line for competition and duty shooters who want more rounds on tap and a faster, more reliable reload. The added weight at the base of the magazine also helps an empty mag drop free under recoil spring pressure, which speeds up transitions between magazines.

Key Specifications

• Adds 4 additional rounds of .45 ACP capacity to compatible Glock 21/41 magazines, extending your round count before a reload.
• Built from billet aluminum, giving the base pad more rigidity and a more consistent fit than cast alternatives.
• Finished with hard anodizing for a durable, color-fast coating that resists wear from repeated reloads and holster use.
• Uses a patented push-pin design to lock the base pad to the magazine, allowing quick field stripping for cleaning between range sessions.
• Installs as a one-piece unit with no extra parts or tools required beyond the included pin.
• Machined and assembled entirely in the USA, keeping production and quality control in-house.

Do I need tools to install it? No. The push-pin design lets you slide the base pad on and lock it in place by hand, and the same pin makes removal just as easy for cleaning.
