Ruger LCP Flat Trigger Upgrade (LCP1 Only) – Install Guide & Trigger Pull Overview

This video walks through the installation of the M*CARBO Flat Trigger upgrade for the Ruger LCP (LCP1 only). The goal is to replace the factory polymer trigger with a precision-machined 6061 aluminum flat trigger to improve trigger feel and provide a more consistent, straight-back press when installed and used correctly. **COMPATIBILITY NOTE:** • WORKS FOR RUGER LCP1 ONLY • DOES NOT WORK WITH EARLY “DASH” SERIAL NUMBER GUNS (e.g. XXX-XXXX) We cover a complete disassembly of the pistol, replacement of the firing pin spring, guide rod, hammer spring, and magazine release spring, along with removal and installation of the new flat trigger. We also demonstrate how to set pre-travel and over-travel adjustment on the trigger, followed by function checks and before/after trigger pull comparisons. The flat trigger upgrade is designed for shooters who want a more predictable, controllable trigger press on the original LCP double-action-only platform, while maintaining safe, semi-automatic operation of the firearm. Actual trigger pull weight and feel will vary between individual pistols and setups.

Remove the magazine, lock the slide open, and visually and physically inspect the chamber to confirm it is clear. Follow all standard firearm safety rules and work in a safe, organized environment. After installing any trigger, spring, or guide rod components, perform thorough function checks and test the pistol at the range with appropriate ammunition to confirm reliable operation. If you are unsure about any part of the installation process or do not feel fully confident performing it yourself, consult a qualified gunsmith.
