Overview

This drop-in trigger is built for large-frame Glock pistols and is intended for shooters who want a flat-face design with a short reset and crisp snap back. It uses an aluminum trigger body with the factory trigger bar and is made to fit Gen 3 or Gen 4 models chambered in 10mm or .45 ACP.

Considerations & Trade-offs

  • Designed for Gen 3 or 4 large-frame Glock models chambered in 10mm or .45 ACP, so it is not a universal fit across all Glock variants.
  • Uses the factory trigger bar, which may appeal to users who want a drop-in option but also means the setup is not a fully reworked trigger assembly.
  • The flat-face design and short reset are specific feel preferences; hunters who prefer a traditional trigger profile may not find it ideal.
  • Product details do not specify installation requirements or included accessories, so compatibility should be verified before purchase.
