3D Thumb Rest for STI – Left Side for Right-Hand Shooter

The Toni System 3D thumb rest for STI pistols is designed specifically for right-handed shooters, with mounting on the left side of the firearm. This accessory is IPSC Standard legal, engineered to enhance grip and control during dynamic shooting competitions.

The diamond-shaped design ensures that the firearm can be safely unloaded without obstruction, while allowing a natural and secure finger position. Its clamshell-shaped support base, angled laterally at 45°, adapts to the shooter’s anatomy for maximum comfort and efficiency.

Featuring a support surface of 21x14 mm and a 40° inclination, it provides stable thumb positioning to reduce recoil management fatigue. The hole spacing is 9.5 mm, and screws are included in the package (may require adaptation depending on the firearm).
