Interference fit problem on 1911 slide

[rescuerigger]

Problem: I have a new full size parkerized Springfield Armory (SA) 1911 slide from a "Loaded" model that will not fit on a 40 year old full size parkarized SA "GI" frame. The rail cuts on the slide are just toooo tight and I can only get it about 1/2 inch onto the frame.

I would like the new slide cut to fit to the frame instead of the frame fit to the slide, if that makes sense. It just has to shoot reasonably well, no acurizing necessary. I fit the old busing and barrel and they seem to fit well on the new slide.

Am I barking up the wrong tree here? Any recommendations on someone to do this basic work?

Thank you for you time

I completely understand you wanting to fit the slide to the frame, not vice versa.
However, depending on where the clearance is lacking and why, sometimes the frame needs tweaking for the best final result.
If this is going to be a permanent install, do whatever it needs to be tight and right.

Any recommended smith for this basic fit in SF bay area?? I don't need a high end custom shop.

You could always use a very fine file and a lot of fit checking in between

If it goes on half way as you said it must not be THAT far off.

Put some Dykem, Sharpie, or any other thin coat of something on the ways and see exactly where the high spots are then go from there. There's a good chance you'll be able to do the work yourself with simple tools.
