Glock Brass Frame Weight, Gen 3-5

Glock Brass Frame Weight Gen 3-5 (Brass)

The Glock Brass Frame Weight (Brass Frame Weight) from Toni System slides onto the frame rail, shifting additional mass to the front of the pistol. Made from solid brass, it weighs in at around 140g, significantly more than the aluminum version — this keeps the muzzle noticeably steadier when firing, reduces muzzle flip, and ensures more controlled shots. This allows for faster and more precise follow-up shots, making this component particularly interesting for IPSC and competitive shooting.

On each side, there are four threaded holes, allowing for the optional mounting of a Toni System thumb rest on either the left or right — this further defines the support hand position and stabilizes the grip. The Frame Weight is designed for full-size Glock models of Generations 3, 4, and 5. For the Gen 6 series, the Frame Weight for Glock Gen 6 is available separately.
