Polymer Action Enhancement Kit for Slim Frame Glock®

This Polymer Action Enhancement Kit for Slim Frame Glock® pistols replaces the factory trigger, trigger bar, and connector with a drop-in assembly designed to reduce pre-travel, overall travel, and reset distance while smoothing uptake and reset. The result is a clean rolling break averaging 4.5 lbs, with no permanent modification or fitting required. The Nickel-Teflon coating on the trigger bar and connector ensures corrosion resistance and consistent performance over extended use.

FAQ

Will this kit work in my Gen5 Slim Frame Glock?

No. This kit is designed for Gen4 and earlier Slim Frame models (42, 43, 43X, 48, and their MOS variants). Gen5 frames use a different trigger housing and trigger bar geometry.

Do I need to modify my frame or trigger housing?

No. This is a direct drop-in replacement. Remove the factory trigger, trigger bar, and connector, then install the components from the kit. No filing, sanding, or permanent changes required.

Is the pull weight adjustable?

No. This kit is fixed at approximately 4.5 lbs. For adjustable pull weight, consider a dedicated aftermarket trigger shoe with over-travel and pre-travel set screws. This kit is optimized for reliability and consistent break.
