One of my favorite guns I've ever shot was a AllenM 10mm bobtail commander. It just spoke me, like directly to my soul or something.And I should add, I guess most of the 4" & 4.25" guns from the OEMs are aluminum frame so that's something to consider as well, though of course, I could have Allen cut a gov't model sized gun down to 4.25" as I've seen some of his work doing that and it looks great.
