If you check my albums you'll see 5 different 2" Model 10 snubbies, round butt and square butt. SBs conceal more easily but that's the biggest practical difference.
$400 to $450 would be a standard price. If I wanted another one I'd pay that and not think twice about it.
Personally, I have long thought that a K-frame Model 10, 6 shot snubbie was far and above the better choice than any 5 shot J-frame but I routinely carried J-frames, anyway. Years ago I carried K-frame snubs in my motor vehicles. Why I went to J-frames I am uncertain but I am moving back to K-frames for most concealed carry purposes.
You will be VERY happy with that Model 10-5 snubby!!!
