When I was in Quantico in 1991 this is what i remember, it was only issued for a short time, then the switch to glock 17. The "lite" 10mm did not work very well, they never could get the spring weight and timing down Proper main spring and recoil spring work together, by the time S&W figured it out, the 10mm was dropped. You see the gun was designed for 10mm, the FBI wanted the round with lower recoil, so function went out the window. oh well here comes 40 cal.
