Reduce the trigger pull weight and take-up while adding a faster reset and much smoother overall trigger feel in your single-stack slimline Glock. In most cases, trigger weight will be reduced to 3.5-4.5lbs (down from 5.5-7.5lbs from the factory).


This kit fits all single-stack slimline Glock models, including the popular G42, G43, G43X, G48, and more.

Looking to upgrade your double-stack G19, G17, or G34? TTI offers a separate kit for those models, available here.


  • 1x TTI GM Connector
  • 1x TTI Trigger Return Spring
  • 1x TTI Firing Pin Safety Spring
  • 1x TTI Stainless Steel Rear Pin


The included stainless steel trigger pin does not provide any marked performance benefits, but serves as a visual indicator that this kit is installed in the pistol in place of the factory components. The use of this pin as a visual aide is optional, but is highly recommended.
