The last time I handled a S&W 66, was a funny story. My Son and I were visiting Phoenix Arizona. A friend of mine was a Sgt. in the City Police.
Chris is long retired.
We were invited for a ride along, our Glock 17s were left in the trunk of our rental (dept. policy) this was years ago.
My young driver, John, said "I saw you had to leave your pistol behind?"
"Are you familiar with a Mod 66 S&W?" Affirmative. "There is one in the Glove Box" Loaded with .125g .357 Hollow Points. What was left of the box of 50 as well.
That made the 4 hours with this nice young Officer feel better!
You know you are getting old, when Police Officers look like Boy Scouts, with guns!
