From reading some other posts of yours I understand you are after weight savings by using this upper. How many ounces are we talking about?

No forward assist shaves 1+ oz.
(which is now where someone will wander in and blather on about "all of this for an ounce" or some other waste of typing)
Not from me.
I've had a couple of idiot tight Baer 1911s.
Just don't see what they thought was so cool about a mainspring housing that had to punched out of the frame and then hammered back in.
I wouldn't be molesting any of my good lowers with that upper and a hammer. Fit the upper.
I cant but help but to wonder if the Leas bear lowers would fit it better??
Or if it would be even tighter with the two of them together.![]()

Make sure there isn't a burr on the pivot pin first, where the retaining pin slot is machined.
I purchased a used Del-Ton upper reciever for cheap off of the EE a while back. I used it to build a dedicated .22 for my son, on a Stag lower. I had fit issues, to the point that the takedown pin had to be hammered in while at the same time forcing the recievers together. It turned out that the problem wasn't the pin holes, but rather the milling of the recievers not mating up. It turned out that the Del-Ton upper was a fraction too long in the rear. I was able to remedy this with a emory board. I wasn't afraid to do this to this reciever because it to be used as a .22 only. In the attached picture you can see what little bit of material had to be removed, and now the two close up easily and with no slop.

Good info Matt, thanks.
I know this will sound ghetto, but sometimes just using a standard drill bit close enough to the hole size will work too. I would try to do it by hand at first. Just manipulate it in and out and spin it in circle while rotating at the same time. Sit around and watch tv while taking your time. The hole will open up. If you need to go faster, use a drill at very low speed. But mount the drill to a table so it is solid. Its too easy to tip the drill and easier to maintain the proper plane with the lighter upper.
I know this is ghetto... but if you want to spend the cash, you could also bring it to a machine shop.
