The Care and Feeding of Pistol Optics — GMP # 185

This guide details the proper mounting procedure for pistol-mounted optics, emphasizing the use of specific tools like inch-pound torque wrenches and Loctite 248. It stresses the importance of dry fitting, degreasing, incremental torquing, and a 24-hour curing period to ensure reliability. The content also touches on zeroing strategies, optic types (open vs. closed emitter), and routine maintenance for pistol optics, drawing on the expertise of Gunsight Academy instructor Eric Gelhouse.

Quick Summary

Properly mounting a pistol optic involves a multi-step process: dry fit, degrease, apply Loctite 248 to screw threads, incrementally torque screws to specification using an inch-pound wrench, and allow a 24-hour cure. This method, recommended by the LA Sheriff's Department, ensures reliability and prevents optic failure.

Frequently Asked Questions

What is the recommended method for mounting a pistol optic to ensure reliability?

The recommended method, pioneered by the LA Sheriff's Department, involves dry fitting, degreasing components, applying Loctite 248 to screw threads, incrementally torquing screws to specification, and allowing a full 24-hour cure period before live fire.

How do you properly torque optic mounting screws?

Use an inch-pound torque wrench and incrementally tighten screws: first to 50% of the manufacturer's spec, then 75%, and finally to the full specification (e.g., 20 inch-pounds). This prevents over-tightening and ensures a secure mount.

What is the difference between open and closed emitter pistol optics?

Open emitter optics have exposed emitters and are lighter, potentially better for concealed carry. Closed emitter optics are sealed against weather and debris, offering greater durability for duty or harsh environments.

What is a good zeroing distance for pistol optics with 9mm ammunition?

A 15-yard zero is recommended for 9mm ammunition. This distance ensures your point of impact remains within an inch of your aiming point out to approximately 50 yards, making it practical for most defensive scenarios.
