My first Smith & Wesson was a 2.5" 686-6, which I got to replace a Detective Special as my carry gun. On a particularly hot day out and about I had sweat heavily on the Detective Special, and by the time I got home the backstrap had pitted very severely. To this day I don't know if my sweat is especially corrosive or if the Colt was just easily corroded (I've never had that problem with any other blued gun, also it was one of the 90s Colts), but I decided I wanted a stainless gun instead, and the fact it was in .357 Magnum also appealed to me.
I had a really hard time finding a holster that would work for me, and in the end converted a nylon belt holster for a 6" medium frame revolver into an IWB holster for the 2.5" gun which worked reasonably well.
In the end I had to sell the gun, but I've subsequently had the pleasure of acquiring an identical one, and had a nearby saddle maker make me up a custom leather holster patterned after the nylon holster I had made, but with some minor improvements. It's still my carry gun
