Good for gen 5 only imo - Overwatch Precision Polymer DAT Drop-In Trigger Kit for Glock

The trigger pull on this kit is very good. It reduces take up significantly and the break is very crisp with a good reset. However, the trigger shoe has been updated on these polymer models to fit Gen 1-5 Glocks. This means it's too narrow on a Gen 1-4 frame, causing the slide release lever and trigger pin to have excess movement. This causes the trigger pin to walk out the right side of the frame (only about 1/8" inch, but it doesn't instill confidence). This may or may not cause issues in the future with slide lock issues or the trigger pin coming completely out, but I didn't want to take a chance with it and will be returning this trigger kit. I'll be getting something else that is specifically for a gen 3 frame to replace it.
