I had a Ruger Sp101 with a 2-1/4" barrel. I sold it and years later bought one with a 3" barrel. It's my favorite wearing around my property gun. Lots of mountain lions here in El Dorado county, I've got trail cam pics of 3 different lions on my property in less than 2 years. In 1981 I bought a S&W model 19 with a 4" barrel. About 8 years ago I bought a model 66 with a 6" barrel. I decided that I like stainless steel but a 6" barrel is only a range gun. I sold both the model 19 and 66 and bought a 66-1 with 4" barrel.
