Frequently Asked Questions

What tools are needed to install a 1911 drop-in trigger kit?

You will need a 3/32" punch, a 5/64" punch, a small hammer, a bench block or vise, a screwdriver for grip screws, and safety glasses to protect your eyes during the installation process.

What are common issues when installing a 1911 trigger kit?

A common issue is resistance when installing the thumb safety. This can be due to the hammer not being fully cocked or the sear shelf on the safety requiring filing to properly match the new sear.

How do I ensure the 1911 trigger kit is installed safely?

After installation, perform crucial function and safety tests. The hammer should not fall when the trigger is pulled without the grip safety depressed, nor when the thumb safety is engaged. Ensure proper trigger reset.

What safety precautions should I take during 1911 trigger installation?

Always ensure the firearm is unloaded and clear. Wear safety glasses to protect against potential spring discharge. Be cautious when handling the safety plunger assembly to prevent parts from flying out.
