Will a standard government 1911A1 slide work on a model 70 frame?
I have a spare slide/bushing/barrel assembly that fits a 1911A1 frame. If I come up with a second frame, I can have two working pistols. I see stainless model 70 frames are very reasonable. Read thru some sites looking for info but didn't locate the answer I need. It looks like it should work, since the differences centered around barrel stability (finger bushing in the early 70s followed by return to full bushing later...none of which seem to demand a frame change).
Help? Thanks.There are two kinds of guns. Those I have acquired, and those I hope to.

Should work with minor fitting.

Thanks. Meanwhile, I think I mistook a bid price for a set price. :-(

I have not messed with .45's for about 40 years, but I believe they also changed the feed ramp angle on the series 80. A series 70 should work, but like the previous poster said "With minor fitting". Not because of changes, but because of dozens of different manufacturers. Same problem you get with all the black gun parts.

70 has no firing pin block. Series 80 has one. So your block won’t get deactivated. Firing pins probably won’t exchange but I am not sure. I am sure I read somewhere what you want to do won’t work, but I think people removed the system on 80s to improve trigger pull. The fingers were on gold cup bushings and were for target loads like the recoil springs used on them.
