I have the 5" J-frame's .22 LR sibling - the 5" 63. Looks similar, but should not be as muzzle heavy due to the shorter lug than the 5" 60. Well, it does have a smaller hole in it's one piece barrel. The 8-shot .22 LR, SKU #162450, weighs 28.1 oz, while the 5" 60, SKU #162440, is reported as 26.3 oz, both from the 2008 catalog (Earlier catalogs had the 5" 60 at 30.5 oz!). All of the 5" 60 examples I've seen came with the same rubber grips as the 5" 63 - and a two piece barrel, where the 5" 63 has a one piece.
Here is my 5" 63, sporting a HiViz front sight and Model 60 wood grips:
The 5" 63 had a shorter run - only in the 2008 & 2009 catalogs - while the 5" 60 was in 2005-2008 catalogs. I bought mine from the estate of a range buddy. I had to shoot it - it needed wood grips, springs, and a HiViz front sight. Fun plinker - decent balance. I know a dealer who still had, at least at Christmas, a new-old-stock 5" 60 for $589. I've thought about it... bought a new 60 Pro instead just over a year ago. I still think about it...
The 5" 63 has sentimental value - I'll likely keep it. I bought a new 3" 63 11/10 - I shoot it a lot more than the 5". Heck, I bought the LNIB 4" 651 shown 10/11 - and have probably shot it more! I guess that is why I haven't grabbed that 5" 60... YMMV.
