The Glock A.R.T. Gen 3 Large Frame is a precision drop-in trigger upgrade that adds mechanical reset assistance to your big-bore handgun. Tailored specifically for Gen 3 large frame double stack models in 10mm and .45 ACP, the A.R.T. system harnesses energy from the slide’s movement to actively drive the trigger forward—delivering a fast, crisp, and tactile reset that outperforms factory setups. This kit includes all the same high-performance components as our standard Gen 3 offerings but is optimized for the robust demands of 10mm and .45 ACP platforms, ensuring seamless integration across full-size, compact, and subcompact frames. Ideal for high-recoil training, competition, or defensive situations where split-second resets make the difference.
