I've had a 60-15 for a number of years now. I bought it as a carry gun, but it got replaced by my 640-1 when I got it.
No fault of the 60-15 though. I still use it when hiking in the woods. I keep it loaded with some 158 grain .357's with a pointed tip that my father-in-law reloaded and gave me.
If you buy one, keep an eye on all the screws as they have a tendency to loosen while shooting, especially the one holding the rear sight assembly on and the cylinder release.
Very accurate and fun to shoot little gun!
