I had a 2.5” Mod 19 with the Armalloy finish that was beautiful. Left the hanger and trigger original. The armalloy seemed very durable. Was carried on many hunting trips both in a belt and shoulder holster and looked like new after several years of use. One of those “I’d sure like to have back” guns. Buddy I sold it to had a real nice collection of guns when he died and a dealer came in and bought everything from the widow who had no clue to the value.
