Hand finished aluminium trigger kit designed for a lighter, smoother action. CNC machined and handworked in Italy.

The TR-1 Crocodile Essential Trigger Kit consists of:
  • Black mil-spec aluminium trigger with red aluminium trigger safety. Adjustable pre-travel
  • Mirror-finished trigger bar, polished at different angles
  • Adjustment Allen Key
  • TR-1 velcro rubber patch
  • Waterproof hard case
The ‘Crocodile’ design was inspired by input from professional shooters. The curve takes the form of the index finger resting at an angle, rather than perpendicular, to the trigger. The final ‘step’ acts as an index point, to help keep your finger always in the same position.
Compatible with:

Glock 17 (Gen 1 – 4) / 17C (Gen 1-4) / 17L (Gen 1-4) / 19 (Gen 1 – 4) / 22 (Gen 1 – 4) / 22C (Gen 1-3) / 23 (Gen 4) / 23C (Gen 1-3) / 24 (Gen 1 – 3) / 26 (Gen 1-4) / 27 (Gen 1-3) / 32 (Gen 1-4) / 33 (Gen 1-4) / 34 (Gen 1-4) / 35 (Gen 1-4)C
