I've done more than one and the lug on the bushing you should not have to worry about, it should fit as it is.
Yes, any fitting you do on the bushing, not the slide or barrel. I just double up sandpaper (a rough grit first then a smooth grit) and do the "ring" that slides into the slide first before the locking lug since the lug blocks doing them at the same time. Then I move to the one between the lug and the face of the bushing, there's not a lot of room there. I just double sandpaper where it will fit in there, then grab both ends together stick a finger through the bushing and sand away. I use first coarse to get it where I want it then fine to smooth it out.
Others probably do it different and whatever works for each person, but I like using sandpaper. I just watch tv or something and take my time.
Jerry, I've got an oversize bushing coming in. I've never fitted one, but wanted to give it a try. I'm pretty clear about how to fit the bushing ID to the barrel OD, but have some questions about fitting bushing OD to slide ID.
Specifically, I'm wondering about the "locking lug" on the bushing. Does it normally have to be "fitted" in any way? Or is there enough "slop" in the locking groove in the slide?
Since you've done one of these, do you have any guidance for me? Any tips on how to "sand down" the bushing OD? I'm presuming you make the bushing OD smaller, rather than the slide ID bigger.
No problem cap, I absolutely love working on 1911's and there's just something about doing it yourself that feels just plain good. To me anyway.
