MADE IN USA
SMITH & WESSON
This particular gun is wearing a pair of Pachmayr finger-groove grips, rather than the wood grips (called "stocks" by Smith & Wesson) that came with it. Those are made of goncalo alves wood, and are of the "target" type.
Dad "de-horned" the factory grips after he got the gun, meaning he removed the sharp bottom edges, and he also removed some wood from a hump that made the gun uncomfortable to shoot left-handed (he was a southpaw). Those grips are pictured on the last page of this article.
The Model 66 enjoys a great reputation for accuracy, quality, and durability, as do most S&W revolvers. The pictured gun is no exception.
This revolver will accept and safely shoot both 357 Magnum and 38 Special ammo, including extra-hot 38 ammunition known as "plus-p" (+P) and "plus-p-plus" (+P+). As a general rule, any 357 Magnum revolver will safely handle any factory 38 Special ammo - but never attempt to load or fire 357 Magnum ammo in any 38 Special. Check with the manufacturer of your gun before firing +P or +P+ rounds in any 38 Special firearm.
