Description
Anyone who has spent range time behind a factory Glock knows the trigger is the first thing worth upgrading. The Tyrant CNC I.T.T.S. (Improved Tyrant Trigger System) shoe tackles that head-on, swapping out the stock shoe on your Gen 3 or Gen 4 for a piece machined from aircraft-grade aluminum. It cuts take-up travel by roughly 15% and shortens reset travel by about 10%, so there's less dead space before the break and a quicker snap back into the sear for your next shot.
What the I.T.T.S. Shoe Changes About Your Glock
The standout feature here is the hybrid face. Tyrant blended a flat front with a subtle curve at the lip where your finger naturally rests. The flat portion gives you consistent, repeatable finger placement pull after pull, while the curved lip keeps that familiar Glock feel most of us grew up shooting. The safety blade is also thinner than the OEM version, which cuts down on the finger fatigue you get during long strings of fire. It works out to a trigger that feels more deliberate and less mushy without going overboard.
Fit and Finish on the Gen 3/4 Trigger Shoe
This version wears a matte black finish on both the shoe and the safety blade, so it drops in looking like it belongs. It's built for full-frame, double-stack Glock models across the 9mm, .357 SIG, .40 S&W, and .45 GAP lineup, covering popular Gen 3 and Gen 4 pistols like the G17, G19, G22, G31, and more. Worth noting up front: this listing is the trigger shoe on its own, not the complete assembly with the trigger bar included.
Range, Carry, or Competition
Whether you're running drills at the range, setting up a competition blaster, or refining a carry gun, a crisper trigger pays off every time you press. The I.T.T.S. shoe is a proven, well-regarded piece from a shop that machines aerospace and medical parts, so the tolerances are tight and the quality is there. It's an easy way to make a Glock feel like yours.

Frequently Asked Questions
Does this Glock Gen 3/4 trigger shoe include the trigger bar?
This listing is the trigger shoe on its own, not the full drop-in assembly with the black chrome trigger bar. It's meant to replace the shoe on a compatible factory trigger bar. If you want the complete kit with the 30% power spring and bar, that's a separate Tyrant part number.
Which Glock models does the I.T.T.S. shoe fit?
It's designed for full-frame, double-stack Gen 3 and Gen 4 Glock pistols across the 9mm, .357 SIG, .40 S&W, and .45 GAP calibers. That covers common models like the G17, G17L, G19, G22, and G31. It is not made for the subcompact 43, 43X, 48, or any Gen 5 pistols.
How much does the take-up and reset actually change?
Tyrant lists roughly a 15% reduction in take-up travel and about a 10% reduction in reset travel compared to the stock shoe. In practice that means less dead space before the break and a quicker return to the reset point for faster follow-up shots. The hybrid flat/curved face also keeps your finger placement consistent.
Will this work in a Glock clone like a PSA Dagger?
It's built and tolerance-matched for genuine Glock Gen 3 and Gen 4 frames. Some clones have slightly different internal dimensions, so fitment isn't guaranteed on non-Glock builds. For the best results and reliable function, stick to authentic Glock pistols and have the install checked by someone comfortable working on the platform.
