Frequently Asked Questions

What are common issues with 1911 sights?

Common issues include sights loosening up over time, leading to the front sight exiting the slide or the rear sight becoming loose and falling out, often due to vibration or improper installation of set screws.

How can I fix loose sights on my 1911?

If sights are consistently loosening, consider professional gunsmithing, using Loctite on set screws, or replacing the slide if the dovetail or sight mounting points are worn or damaged. This video shows a slide replacement as a solution.

What is a Tisas Series 80 government milspec slide?

A Tisas Series 80 government milspec slide is an aftermarket replacement slide for a 1911 pistol, designed to Series 80 specifications. It's often a budget-friendly option, sometimes sold as factory seconds with minor cosmetic flaws.

What should I do if an aftermarket 1911 slide doesn't fit perfectly?

If an aftermarket slide binds or the safety doesn't engage fully, it may require minor file fitting. Racking the slide multiple times can sometimes resolve minor burrs. Check for burrs inside the slide or frame rails.
