Frequently Asked Questions

How do you safely disassemble a 1911 pistol?

First, remove the magazine and clear the chamber. Then, with the muzzle up, push the plunger and rotate the barrel bushing to release spring tension. Draw the slide back to align the takedown notch with the slide stop, remove the pin, and then separate the slide from the frame. Finally, remove the barrel, spring, and guide rod from the slide.

What is the 'idiot mark' on a 1911 and how can it be avoided?

The 'idiot mark' is a scratch on the 1911 frame, often near the slide stop, caused by improper reassembly. To avoid it, push the slide stop pin directly against the detent until it clicks into place during reassembly, ensuring it's properly seated without forcing it.

What is the 'inversion trick' for reassembling a 1911?

The 'inversion trick' is a technique where you invert the slide and place the frame on top of it. This method automatically aligns the drop link with the slide stop hole, making it easier to insert the slide stop pin during reassembly.

What are the main components removed during 1911 disassembly?

During a full disassembly of a 1911, you will remove the slide stop pin, the slide itself from the frame, and then from the slide, you will remove the barrel bushing, the barrel, the recoil spring, and the guide rod.
