Description
Magazine release button for STI-BUL – Optimized reloading for competition use
The Magazine Release Button for STI and BUL competition pistols is designed to provide a significant ergonomic and performance upgrade. With a larger contact surface than the standard button, it allows for faster, more instinctive magazine changes—crucial during dynamic shooting disciplines.
Installation requires drilling the original magazine button and securing the new component using the included screws. The kit features two screws to ensure full compatibility: one M3 screw for STI models and one 4-40 UNC screw for BUL models. This guarantees a precise fit and a solid, competition-ready installation.
