Different variations of S&W 66...

I just picked up a 66-3 on a private sale. Just curious what differences there are in the variations of this most excellent firearm? Also still trying to find out date of manufacture. Serial BHF87**
Thanks, Koy

A whole lot of commemeratives for different depts/agencies...

Early first year guns have a SS rear sight, which was replaced due to complaints - I was told it was a visual problem for people, esp LE. I own one of those.

The 66 was available in 2.5, 3, 4, and 6 in barrel lengths. There may have been a 5in barrel, special order and I never saw one with an 8 3/8 barrel myself, but they could exist. As another has said, round or square butt was another choice. Around 1980 recessed chambers were removed, and not long after that, the pinned barrels as well.

Many of the changes from a 66, to a 66-1, to a 66-2, were minute, but the factory gave it a model designation change. Many of the changes had to do with production, or internals, and not things like pinned and recessed or not pinned and recessed, which never designated a new dash number. Other things like hammer, trigger options, grip types and sight options never designated a number change either.

Model 66-3's were made from 1986 thru 1993...if you bought a 2 1/2" then its a Round Butt K frame....if you bought a 4" or 6" it should be a Square Butt K frame...

In 1988 within the 66-3 model revision -- is where the 3" first shows an "RSR" gun...but they're uncommon.

Model 66's were shipped with a variety of "stocks" ...including Goncalo Alves(wood) / some with Hougue rubber stocks or Uncle Mikes rubber....and 99% of us that own and shoot a lot of S&W revolvers change the stocks all the time ( I hate the rubber ones / really like the older S&W finger groove wood stocks..) but to each his own...
