from John Harrison's site:
There is a lot of misinformation circulating about beavertail installations on Springfield pistols. First, there are two different frames to consider: the Mil-Spec / WW II frames with original style frame tangs and "Loaded" pistols that come with a factory beavertail.
Loaded model frames are cut for Wilson pattern beavertails and are usually over cut as they come from the factory. To get a nice tight joint, I usually weld the radius and re-fit the stock beavertail or a Wilson. A Group 1 beavertail can be fit, but will require a good bit of weld build up.
Mil-Sec / WWII frames have G.I. style frame tangs that are shaped a little bit differently from the standard pattern. The tangs are a little shallow on the topside and when fit with a Group 1 beavertail often has a gap or mismatch on the top face of the frame to beavertail joint. This is not in every case, but in most. To avoid this mismatch, a small weld bead can be placed on top of each tang to add enough material to the tang to make a smooth joint. Group 2 beavertails can be fit without this extra welding. This frame is what the S&A .220" radius beavertail was designed for. S&A uses a smaller radius on this safety that moves the joint forward to where the frame tangs are thicker.
