In the early 80's, when I worked that small department, my duty rig weight 13.5 lbs. Didn't know that till I weighed it one night on a big digital scale.
Colt 1911 with 4 mags. in pouches, double handcuff case w/2 sets of handcuffs, radio, mace, the belt, holster, mag pouches, radio pouch, mace pouch, and four keepers to keep it lined up with my pants belt. And two of those long heavy duty tie wrap temporary/one use cuffs in the sweatband of my hat. Never used those either, but I carried them, every day. Only cuffed one guy in 4 years. Never pulled the gun (1911) on anyone. Old days, old ways.
Oh, you couldn't have paid me to carry a 9MM in those days. Now I carry one fairly often.
