Machined aluminum slimline Glock trigger shoe with a pre-travel adjustment screw, sold with a matched trigger bar.

Almost every slimline Glock trigger is polymer. The Tyrant CNC I.T.T.S. is not: the shoe is machined aluminum with a stainless steel safety blade, and it carries an adjustment screw that sets pre-travel rather than leaving take-up wherever the factory put it. On a Glock 43X or 48 with a short trigger reach, the metal face and the squared profile give a noticeably more defined index than the rounded factory shoe.
Buy the version with the trigger bar. Tyrant sells the I.T.T.S. blade on its own at a lower price, and that shoe-only part expects you to reuse the factory bar; the trigger-with-bar package is the one that changes how the whole press feels. Both come in anodized color combinations across the shoe and safety screw, which matters only if you are matching a slide.
Add the I.T.T.S. Trigger with Trigger Bar (G43/43X/48) to your build and see how it enhances your platform.
