Pinned & Recessed

[Condonse]

I see guns for sale and it says "pinned & receesed" in the description. Is this something that Smith & Wesson does in the factory or is it a custom modification? I saw a 66-1 listed with it and I just bought a 66-2, does that mean mine is pinned & recessed?

Here is a picture I found on google that will explain it far faster than I could type:

The -2 engineering change on your Model 66 is the one that removed the P&R in 1982, so your gun will not have these features.

Up until around the mid-80s, ALL S&W barrels had a pin going through the frame at the top that mated to a notch in the barrel. It kept the barrel from unscrewing. Now days, they are just 'crush' fit (or have a barrel shroud around a barrel liner).
'Recessed' refers to the chambers being countersunk so that the sides of the rim fit all the way down in the cylinder. This was ONLY done for MAGNUM calibers and RIMFIRES. For the K-Magnums, I think this went away after the 19-4 and 66-1 if memory serves.

Actually, the barrel pin revision was made in 1980 I believe. The fact of the matter is that all barrels, whether pinned or not are "crush" fit. The pinned barrels are not just screwed into the frame hand tight and then the pin is installed. I think the pinned barrels thread into the frame and are hand tight 60 degrees before the reach their final vertical position. Hand tight means that the components cannot be tightened by hand any further. Then wrenches are used to move everything into it's final position.
