Frequently Asked Questions

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

Essential tools include a screwdriver for grip screws, 3/32" and 5/64" punches, a small hammer, a bench block or vise, and safety glasses. These are necessary for safe and effective disassembly and reassembly of the 1911 frame.

How do I know if my 1911 thumb safety needs fitting after installing a new trigger kit?

If the thumb safety resists installation, first check if the hammer is fully cocked. If it is, the sear shelf on the thumb safety may need to be carefully filed to match the dimensions of the new sear for proper engagement.

What are the critical safety tests after installing a 1911 trigger kit?

Crucial tests involve ensuring the hammer does not fall when the trigger is pulled without the grip safety depressed, and also when the thumb safety is engaged. Proper trigger reset must also be confirmed.

Can I test my 1911 trigger installation by dropping the slide on an empty chamber?

No, repeated 'Drop Testing' by dropping the slide on an empty chamber is strongly discouraged. This action can damage or break the sear surfaces of the 1911 pistol, compromising its function and safety.
