How do you assemble a 1911 A1 45 ACP?

Answer 1

Insert the barrel into the slide. On the barrel, behind where the recoil spring guide sits, you'll find a barrel link. Rotate that link up so it's perpendicular to the barrel. Insert the barrel bushing and rotate it clockwise until it stops. Then install the recoil spring guide. Being mindful of that link remaining perpendicular to the barrel, slip the frame onto the slide and pull it back until the takedown notch is aligned with the rectangular cutout on the frame, and you can see through the barrel link when looking through the slidestop hole. Install the slidestop pin through the slidestop hole and barrel link until it sits flush against the frame. Make sure the bushing is fully turned clockwise and install the spring and plug onto the recoil guide rod. compress the spring until you can maneuver the barrel bushing wrench over the bushing with the plug and spring under it. Compress the spring with the wrench while turning the bushing counterclockwise enough to lock the plug in place. Cycle the action to make sure you got it, and you're done!
