About the average price these days... Don't know what those people are thinking pricing a 3" more than a 4"... The 3" has the InterLock and is MUCH less desirable a gun...
I have an early one that I had a .22 Magnum cylinder fitted to...both rounds shoot great.
I knew the older ones were sought after, but I did not realize that they cost so much.
Fun guns. I personally shoot a K frame .22, like my Model 18, better, but the Model 63 is still fun, and is so light, I forget I am wearing it. Great fishing companion during snake season.
NMpistolero: I want to thank you for bringing this subject up as I am currently dealing on another Model 63. The owner has not yet set a price on his older but minty Model 63 with the 4" barrel. I bought all my currently owned Model 63's (and a 651!) new, years ago and am in a bit of sticker shock whenever I see a used older Model 63 at a gunshow or in a gunshop! They do command strong prices. I would be glad to pay the $620.00 you mention for the minty Model 63 that I am dealing on. I don't think you would loose much money at all if you paid the $620.00 for your Model 63 and should you decide to sell it in the future. You might even make a fifty dollar bill. I hope some more folks will chime in on current values of the older Model 63's. Hold into the wind VarmintGuy
Check the yoke end shake, lots of older 63's and 34's had the yoke screw swapped with the slide plate screw...yoke screw is fitted to the yoke. If the cylinder flops out when you open it, it's got a lot of use over the years or some idiot swapped out the screws. It can be refitted but it's a PITA to do it.
The last non lock, non MIM (forged hammer and trigger) versions have a different yoke retention set up. If you find one of those grab it.
63's in nice to very good condition are like hen's teeth here. Very seldom see them in the LGS's and pawn shops. You'll see an 18 more often than a 63.
When you do see one, they're more than likely going to be asking closer to a grand than $600.
