Frequently Asked Questions

What is the recommended method for conserving a vintage 1911 pistol's parts?

A professional gunsmith recommends submerging firearm parts in a boiling water bath for about an hour. This process effectively converts red rust to black oxide, removes old oils and cosmoline, and cleans the components without damaging the temper of springs.

How does the 1911's firing pin design ensure drop safety?

The 1911 features an 'inertial' firing pin that is shorter than its channel. This design, combined with spring tension, ensures the firearm is drop-safe, as only a direct, high-velocity strike from the hammer can overcome the spring resistance to fire a round.

What are common mistakes to avoid when maintaining a 1911 pistol?

Avoid forcing the magazine release screw, which can break the internal lock. Also, be cautious not to bend the three-leaf sear spring, as its precise tuning is critical for the sear, disconnector, and grip safety functions.

What is the difference between Series 70 and Series 80 1911 slides?

The primary difference lies in the firing pin safety mechanism. Series 80 1911s incorporate an inertial firing pin interlock system for enhanced drop safety, which is absent in the Series 70 models.
