What to Know About Smith and Wesson Model 66-2 Serial Numbers?

I’m looking for some insights into the serial numbers on the Smith and Wesson Model 66-2 revolver. I recently inherited one from my grandfather, and I want to better understand its history and how to identify important details.

Here are a few specific things I’m curious about:

  • Dating: How can I determine the production year of my Model 66-2 using the serial number?
  • Authentication: Are there any key indicators in the serial numbers that can help verify the authenticity of my firearm?
  • Production Runs: What are the known production runs for the Model 66-2, and how should the serial number reflect these?

If anyone has resources, tips, or experiences they’d like to share regarding these revolvers, I’d greatly appreciate it! Looking forward to learning more about this classic piece!

I’m glad you brought this up! The Smith and Wesson Model 66-2 has specific serial number ranges that can help you date the firearm accurately. Generally, they were produced from 1970 to 1986. The serial numbers are typically found on the butt of the grip.

That’s true! Also, keep in mind that a smooth trigger and the size of the cylinder can vary between different production years. It’s these small features that can tell you a lot!

I think it’s fascinating how each generation of the Model 66-2 shows different design elements. I have a late '70s model and the finish is beautiful compared to newer versions. Anyone have experience comparing the finishes?

I have an early '80s Model 66-2, and I noticed the bluing is different – it seems less durable. I wonder if S&W changed suppliers during those years.

That’s interesting, cindy99! I read that S&W sometimes adjusted their production methods based on cost and materials. If you’re looking to date your firearm, check the cylinder release; it’s a telltale sign of the production era.

I thought the cylinder release was pretty consistent throughout the production. What specific characteristics should I be looking for?

Good point! I’ve also noticed earlier models had slightly different grips. Has anyone here swapped grips on theirs? How did it turn out?

I changed the grips on mine! It made a huge difference in the feel. I went with a classic wood style. It’s worth it for the aesthetic, for sure!

By the way, what’s the serial number for the 66-2 typically start with? It’d be helpful to know if my model is within a certain range.

It starts with a ‘K’, but there are examples with a ‘D’ too — mainly from the later years. A quick lookup on S&W’s records should help too!

So, if someone has a Model 66-2 starting with D, does that mean it’s lesser quality? I heard some rumors that later production was not as good as earlier.

I think that’s a myth! I’ve seen plenty of well-functioning models from the '80s. It really depends on individual care over the years.

I wonder how many people have inherited these models? Mine was passed down from my grandfather. There’s a sentimental value that just can’t be measured!

Absolutely! Firearms like these are often family treasures — and they carry stories too! Which makes them even more unique.

I recently bought a Model 66-2, and I’m curious about how the serial number affects its value. Can anyone share insights on this?

Serial numbers can definitely impact value! Generally, earlier production numbers are more sought after. It’s all about rarity and condition!

Condition is crucial too! I have one with a low serial number, but it’s nicked up. How does that affect things compared to a higher number in perfect shape?

A low serial number can add value, but condition will always be king when it comes to appraisals. It’s a balance.

What about historical significance? I heard these revolvers were popular in a few significant police departments. Does that factor in?
