I bought one a few years ago after reading good reviews from other owners. Mine has the concealed (bobbed) hammer, fixed sights and DAO trigger. In other words, it's in "belly gun" mode. It will fit in a K frame holster, but trying to find aftermarket grips is a real challenge. Pachmayr makes a set of rubber combat grips that help, but I haven't been able to find anything else that will fit. Mine has an excellent double action trigger pull. The 720 uses a coil mainspring like a J-frame, and the rest of the mechanism will be very familiar to anyone familiar with the internals of a S&W revolver.

Best of luck,

Dave
