This video explains how to adjust the trigger weight on a 1911 pistol. The primary method involves tuning the mainspring, which is responsible for the trigger's resistance. It's also possible to purchase pre-tuned springs. The speaker notes that while increasing trigger weight is possible, it's less common given the 1911's 'cocked and locked' carry method.

Quick Summary

The trigger weight on a 1911 is primarily determined by the leaf spring in the rear. You can adjust it by tuning this spring or by installing pre-tuned aftermarket springs designed for different pull weights.

Frequently Asked Questions

How can I change the trigger weight on my 1911 pistol?

You can adjust your 1911's trigger weight by tuning the existing leaf spring, which dictates the trigger's resistance. Alternatively, you can purchase pre-tuned springs specifically designed to alter the trigger pull weight.

What part of the 1911 controls trigger weight?

The primary component responsible for the trigger weight on a 1911 is the leaf spring located in the rear of the firearm. Its tension directly influences the resistance you feel when pulling the trigger.

Is it common to increase the trigger weight on a 1911?

While possible, increasing the trigger weight on a 1911 is less common. Given that the 1911 is often carried 'cocked and locked,' a lighter trigger is generally preferred for faster deployment, making heavier triggers less desirable for most users.
