Smith & Wesson M&P Trigger Upgrade | Smith & Wesson M&P Disassembly | M*CARBO

This video is an educational, step-by-step demonstration showing how a qualified individual can install a Smith & Wesson M&P trigger upgrade kit and perform a detailed disassembly/reassembly of the pistol in a safe, controlled environment. It is intended for informational purposes only.

The goal of this upgrade is to provide a lighter, smoother trigger pull and improved overall trigger feel for Smith & Wesson M&P pistols in 9mm, .357 SIG, and .40 S&W. M*CARBO aftermarket parts are American made by Combat Veterans and are engineered to maintain the factory safety features and semi-automatic operation of the firearm. This upgrade does NOT convert the pistol to automatic or simulated automatic fire and does NOT remove factory safety devices.

• Custom Smith & Wesson M&P trigger upgrade for a lighter, smoother trigger pull
• Performance-focused M&P 9mm / .40 / .357 accessories for improved accuracy and control
• Detailed M&P slide and frame disassembly with trigger component sanding and polishing
• Smith & Wesson M&P trigger kit installation walkthrough with spring replacement
• Competition-ready Smith & Wesson M&P upgrades for consistent, repeatable trigger performance

ALWAYS follow all federal, state, and local laws. Ensure your firearm is completely unloaded before performing any work. If you are not comfortable working on your firearm, please consult a qualified gunsmith.
