All my Handis are on dedicated frames. I always try to keep two or three extra SB2 frames around to find the one that fits the new barrel best. I started this practice 3 or 4 years ago, and now I have none that need shimming or tinkering. I took a little off the latch shelf on one, and that was it. I had a .357 that was shimmed at the pivot. I put it on a different frame and it is fine. It put Richard, Atllaw, right out of work making shims.
If I can ever get to Jawja, I'll get together with him and practice.....just in case.....ya never know when you'll need a shim.
