What can you tell me about these markings?

[Zoti]

I have a S&W model 66-6 and as you can see in the picture, there is a "970" engraved on the cylinder swing. It is also engraved on the bottom of the frame and frame cover.

I was told it is a mark they make at the performance center. I am not the original owner of the gun so I don't know the history.

Does anyone know more?

Parts identification while being built - and might be part of the gun serial number if it wasn't scribbled over with a marker...

Will also be found on the back side of the sideplate. In S&W circles it is known as an "Assembly Number". Has nothing in common with the serial number. Not unique to any one gun. Smith may reuse the numbers, rolling them over every so often.

I have seen other guns and they do not have those numbers.

It does not match any part of the serial number.

I bet someone other than S&W did that.

The locations, size and number of digits (and the number itself) in assembly numbers varied throughout the years. Some were stamped and other (later ones, since about the year 2000) laser engraved. They will not be part of the SN unless there is a happy coincidence, but if you look hard enough you will find them in nearly all S & W revolvers. Sometimes they come with letter(s) and are as long as 5-6 characters total.

There will always be an "Assembly number" on S&W revolvers. It is found on the Yoke, inside of Sideplate and parallel to the bottom of the grip frame on the left side, below the stock pin. Usually it is stamped in letters less than 1/8" high, but in later years it can be seen dot-matrix stamped, laser etched and in larger numbers as this one is. Whether any of you choose to believe this or not, that is what the 970 marking on this revolver is!

If the assembly number corresponds in any way to the guns serial number it is purely coincidental.

What do the numbers next to the trigger and hammer mean? On that flier.

How wide the trigger and hammerspur are in thousandths of an inch.

Why does it matter?

Why does it matter?

The same reason they tell you the barrel length. Some people prefer different things. Wide 'target style" versus more narrow
"service" or "combat" style.

Does anyone know anything about the trigger stop installed behind the trigger in my gun as seen it the pictures above?

This gun for instance, is about 1000 numbers from my gun and is also a 66-6 but does not have the trigger bump.
