This video provides a detailed, step-by-step guide to reassembling a 1911 pistol after a complete field strip. It covers the installation of all internal components, including the trigger, sear, disconnector, hammer, and safeties, emphasizing proper alignment and lubrication. The process extends to slide assembly with the firing pin and barrel, concluding with a crucial function check.

Quick Summary

Reassembling a 1911 involves installing the trigger, magazine catch, sear, disconnector, hammer, and safeties into the frame. The slide is assembled with its internals, including the barrel and recoil spring. Finally, the slide mates to the frame, and a function check confirms proper operation.

Frequently Asked Questions

What are the key steps for reassembling a 1911 pistol?

Reassembly involves installing the trigger, magazine catch, sear, disconnector, hammer, sear spring, mainspring housing, grip safety, and thumb safety into the frame. Then, the slide internals (extractor, firing pin stop, firing pin, barrel, recoil spring) are assembled, followed by mating the slide to the frame and installing the slide stop and bushing.

What tools are useful for 1911 reassembly?

Essential tools include a punch for alignment (acting as a slave pin), a small amount of gun grease for small parts, a brass-headed hammer for pins, and a barrel bushing wrench for final slide assembly. A cleaning mat is also helpful for organization.

What common mistakes should be avoided during 1911 reassembly?

Avoid scratching the frame when installing the magazine catch screw. Ensure correct alignment of parts like the hammer strut with the grip safety. Always perform a function check at the end to verify all components operate correctly.

How do you install the sear spring and mainspring housing on a 1911?

The sear spring (leaf spring) is seated in its slot at the bottom of the grip. The mainspring housing is then partially slid up to hold the sear spring in place before being fully seated and secured with its pin.
