Sig Sauer P365 Short Stroke Flat Trigger – Install Guide & Trigger Performance Overview

The M*CARBO Sig Sauer P365 Short Stroke Flat Trigger is a precision CNC machined upgrade designed to refine trigger feel and reduce unnecessary travel compared to the factory trigger. In this video, we walk through range demos, trigger break comparisons, and a complete step-by-step installation so responsible P365 owners can better understand how the trigger works and how to install it correctly. We start by showing the stock trigger at the range, then compare factory break characteristics to the M*CARBO flat trigger. From there, we cover a detailed look at the OEM MIM flat trigger, discuss the MIM process, and then demonstrate how the new Short Stroke Flat Trigger changes break angle, reset, and travel when properly installed. The video ends with a full fire control unit (FCU) breakdown, reassembly, and live-fire demos with the upgraded trigger. This trigger is compatible with multiple P365 models, including the Sig Sauer P365, P365 .380, P365 SAS, and P365 XL.

Actual trigger pull changes and overall feel will vary between individual pistols and setups. Any set screw or pretravel adjustments should be minimal, focused only on proper engagement, and must not remove or defeat safety features. Safety & Responsibility: Always verify that your Sig Sauer P365 is completely unloaded before beginning any work. 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 any trigger or striker spring changes, 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 or adjustment process, or do not feel fully confident performing it yourself, consult a qualified gunsmith.
