The 10-7 at about 32 years old is actually not that old - just may appear that way because of the modern plastic gun craze now days. It is one of the most popular S&W models and was carried by almost all the Country's PD's at one time or another. While not a "sexy wonder nine" it will do what ever you ask of it (within it's capability of course) and like a Timex - take a linckin' and keep on tickin'
They are accurate, reliable, robust, and a pleasure to shoot! Your M10-7 will handle any commercially loaded .38 Special including +P's but will wear slower with standard velocity ammo.
