hi y'all.
need some expert advice here....
situation: just installed a "drop-in" barrel in my 1911 this afternoon. took a little work with a file to achieve lockup. took the following measurements once lockup occurred: in battery position- .132 in. between top of barrel hood and top of slide. 1/8" out of battery position- .176 in. between top of barrel and top of slide. gave me a difference of .44 in. as I understand, .44 in. is acceptable, so I thought I was making good progress. I cycled the slide with just the barrel and lapped-in bushing installed, and it hung up once in about 15 cycles. i then installed the barrel and bushing into the slide, mated the slide and frame, and installed the recoil spring (18 lbs) and recoil spring guide (short/standard). once I did this, I noticed that in "battery" position, the back of the slide is forward of the back of the frame by .055 in.
While hand cycling, I also noticed a slight "hitch" at the beginning of the cycling motion (about .022 in.) while the barrel still appears to be in battery. from the sound it makes, I believe it is the recoil spring causing the "hitch", but I don't know. What is causing this?
I then decided to install the slide stop to see if that would cure the “hitch” and marry the back of the slide to the back of the frame. No dice. I couldn’t get the slide stop completely installed. When I tried to do this, I had to cycle the slide approximately .25 in. rearward and once the slide stop pin inserted through the link pin, it completely locked up the pistol with the back of the slide resting .017 in. rearward of the back of the frame..
I then attempted to fully cycle the slide by applying downward pressure on the barrel hood, but could not make the barrel hood to drop at all.
In all, it appears that I have multiple issues here. Can’t seem to diagnose the problem here. I'm starting to suspect that the link that was installed on the "drop-in" barrel may be too long, but would this explain the rest of the problems? Checked the manuals and videos I have, but I am seriously confused at this point. Any help would be greatly appreciated.
