Frequently Asked Questions

What are common causes of malfunctions in a 1911 pistol?

Common causes include worn or damaged magazines (fatigued springs, widened feed lips), and worn-out recoil springs. Issues with the firing pin retaining plate, slide stop lobe, and loose plunger tubes can also lead to malfunctions.

How often should the recoil spring be replaced in a 1911?

For a 5-inch Government model, replace the recoil spring every 3,000 rounds, or more frequently with heavy use. Commander models (4.25-inch) need replacement every 1,000-1,500 rounds, and Officer models (shorter) every 500-700 rounds.

What is a critical maintenance point for the 1911 firing pin retaining plate?

The firing pin retaining plate is prone to cracking on its thinnest left side. Regular inspection is crucial, and replacement with a hardened aftermarket part is recommended if cracks are found to prevent it from falling out.

How can you check for a loose plunger tube on a 1911?

With the slide in place, gently wiggle the thumb safety. Any noticeable movement or looseness indicates the plunger tube is not securely staked to the frame, which can lead to the thumb safety becoming stuck.
