Okay, I was a approached about buying some 1911 stuff. Shown the parts and price I accepted.
Parts was a factory SR1911. Firing pin, spring, and stop were gone. I was told they tried to get it back together but couldn't. Examination revealed frame left side grips screw bushings were stripped.
Payment realizing even if there was a cracked slide the frame was worth the money. Payment was made, MSP protocol followed and 7 days later I picked it up.
First to verify if anything catastrophic had occurred. Nope.
Discovered the frame assembly was an anomoly...or should I say how Ruger is building the full size 1911's now. Ruger's earlier and other full size 45 caliber 1911's use a thinner ejector.
The reason the gun would not go back together is this full size gun was built with a 9mm ejector! This ejector is wider, requires a slide milled for it, and a 45 firing pin stop will not clear it when putting the slide on the frame...conventionally. The feedramp isn't cut super deep. For those of you into caliber conversions on 1911's this means 9mm, 10/40, 38 Super and related case rounds may work. Which is something I may try...not sure, not fond of conversion pistols.
What I did...
~ tapped for and installed oversize grip screw bushings;
~ fitted an EGW flat bottom firing pin stop;
~ tuned the extractor;
~ replaced the trigger and hammer and did a trigger job;
~ refit and blended the thumb safety;
~ adjusted for more shallow grip safety deactivation;
~ recrowned the muzzle, fitted a barrel bushing, and accurized the pistol;
~ deburred the inside of the recoil spring plug and smoothed out the recoil spring guide.
Not a major redo, but to make it a better gun than it was. Now time to test fire.
Before pics attached. Stripped grip screw bushing holes pics also.
