Here's my Pre Model 27, five inch gun. It had a pair of butchered non-relieved target grips on it when I got it. Somebody tried to add a speed loader relief to them and poorly refinished them. I added these Herrett grips as they feel good to my hands.
This gun was shipped in October of 1958, late for a five screw.
Since Charlie likes photos, I'll share a couple of other Model 27's.
No dash 27 with a 6 1/2 inch barrel, shipped in February 1959. It has "coke" grips.
Another five inch, this one a 27-2, Nickel, Florida Highway Patrol gun. (Charlie should remember this one as I got it from him). It came to me with rubber grips so I added another set of Herretts. Shipped in June of 1966
