Ruger Security-9 Trigger Spring Kit – Step-by-Step Install & Disassembly Guide

Описание: In this video, we walk you through the complete installation of the M*CARBO Trigger Spring Kit for the Ruger Security-9, including basic disassembly, internal inspection, spring replacement, and reassembly. This step-by-step guide is designed to help responsible Security-9 owners better understand the factory fire control system and how a trigger spring kit can affect trigger feel and consistency.

The Ruger Security-9 Trigger Spring Kit is intended to provide a noticeable reduction in trigger pull weight compared to the stock configuration. In many setups, users may see an approximate reduction from around a 5 lb factory pull to roughly the 3.5–3 lb range, although actual results can vary by about +/- 1 lb depending on the individual pistol. The goal is a smoother, more consistent trigger press that can support improved control when used properly.

Safety & Responsibility:
Always verify that your Ruger Security-9 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. If you are unsure about any part of the installation process or do not feel fully confident performing it yourself, consult a qualified gunsmith.
