As noted above, the 'pinned' barrel shouldn't be a problem.

Here's another thread on these guns if you haven't read it: Model 10 Gunsmith Special

I bought two of these, and recently finished my first one with a two inch barrel, and bobbed and polished hammer and trigger. Still fiddling with the action.



Number two will most likely get a 4" barrel cut down to 3" if I can't find a 3" barrel. I already picked up a long ejector rod for it.
