I have a 629-1 3" that I bought used.
I also own a 629-4 6 1/2"
I have been told the 3" is a Lew Horton but I don't have any documentation.
My club holds a back up gun plate shoot every now and then and by the rules 3" revolvers are back up guns
It shoots pretty nice, I alternate between the Houges and some smooth wood with finger bumps that actually work better on the 3" than the 6 1/2" gun. With full loads there is plenty of recoil but it is way better than a 357 airweight. The gun is fairly short but still pretty heavy so more of a heavy push than the fastball caught barehanded sting of the light 357s
Most of the loads I shoot in it are 240 cast over a moderate load of unique which runs about 1000-1050fps. Great accuracy , I believe commercial cast bullets are pretty hard and are not getting a good grip on the rifleing at 800 fps or so of the usual 44 special loadings but when you push them up over 1000fps the groups start to shrink.
Its a real contrast , sort of a small looking snub gun which of course it really isn't because the scale is all wrong.
I also have some lighter loads , I believe they are 200 or 210 gr fairly soft cast that I again push with unique to a mild 750 fps-pretty much a mild 44sp load , it's a real pussycat that I have folks try before letting them shoot the mid range load.
And before anybody asks , I am not the guy who sneaks the full power loads in on the unsuspecting . Hate that stupid crap.
