Is there anyone who doesn't like color case hardening? Actual question.... I sure do. To me that gun conjures the first time I held a fairly new Colt SAA, what a fine combo of quality bluing and CCH it had. But first I should comment on the work, and that comment is, beautiful.
.38 and 9mm, gee, wonder which gets used more....
.... and with some of the loadings out there maybe not a great deal of dif on the receiving end.
Tech question about the CCH, I always wondered but never really looked into it. So Karl, how deep and how hard is it, do you know? Not that it matters much, I mean there could not be a "not hard enough, not deep enough" since frames are pretty much accepted as fine as-is, with no case at all.
