This guide details various methods for mounting red dot sights on handguns, from competition bridge mounts to direct slide milling. It covers the pros and cons of different systems like MOS and dovetail mounts, emphasizing proper installation techniques, including torque specifications and the use of Loctite. The importance of optic-cut holsters and protective mounting hardware is also highlighted.

Quick Summary

Mounting a pistol red dot sight involves several methods: bridge mounts for competition, dovetail mounts (use with caution), direct slide milling for lowest height, and modular optic systems (MOS). Always use blue Loctite and a torque wrench set to 12 inch-pounds for secure installation, and ensure your holster is optic-cut.

Frequently Asked Questions

What are the different ways to mount a red dot sight on a handgun?

Handgun red dot sights can be mounted using bridge mounts for competition, dovetail mounts that replace rear sights, direct slide milling for the lowest profile, or factory modular optic (MOS) systems with interchangeable plates. Each method has specific advantages and considerations for stability and height.

Why is proper torque important when installing a red dot sight?

Using a torque wrench set to the manufacturer's specification (often 12 inch-pounds) is crucial. Over-tightening can damage the optic or slide, while under-tightening can cause the sight to shift or detach during recoil, leading to malfunctions and loss of zero.

What is the difference between Trijicon RMR and Holosun red dots?

The Trijicon RMR is known for its exceptional ruggedness and durability, often favored for duty use. Holosun optics typically offer more user-friendly features like side-loading batteries, solar failsafes, and multiple reticle options at a competitive price point.

Should I use Loctite when mounting a red dot sight?

Yes, using blue Loctite (a removable threadlocker) on the mounting screws is highly recommended. It helps prevent the screws from vibrating loose under the stress of recoil, ensuring the optic remains securely mounted and holds its zero.
