Model 13 was my first duty gun
When I started with the I&NS in 1991, they were issuing S&W model 13's. We used the 110 grain jhp in it without problems. These were supposed to be the FBI rejects that the bureau did not want after ordering thousands of them. Instead they went with the 10m.m. and had a complete fiasco.
Department of Justice, just gave those S&W model 13's to all their componets, like I&NS and the U.S. Marshal Service.
With the 110 grain ammo, they worked well, were good carry guns as they weighed about 2 pounds loaded (compare that with the RUGER GP-100 they bought next) and could be carried concealed.
We had some incidents when officers qualified with 125 grain jhp and the forcing cone split. After that, after that, only RUGER'S and S&W L frames got the 125 grain jhp. When I last qualified with my S&W 681 with the 125 grain ammo, they dumped 6 boxes on me just to clear out the supply pf 125 grain ammo.
If you want to carry the 110 grain ammo, you can buy the WINCHESTER White box load as it is the mildest load of this ammo and by far the cheapest. It will also work fine as a self defense load. About equal to a 9m.m. +P 115 grain round.
