Found a Model 64-5 For Sale online that is advertised as a Single action only. Did S&W make a SAO M64?; possibly a special order.
The box for the M64 shows a product code 102504, with SN CCY86XX. Just curious and trying to learn. Your responses are appreciated.

Thanks.

S&W never made a SAO M64. They did make a single action version of the M14.

Does it have a hammer spur? More likely, this is a DAO gun and the owner is unclear on the concept.

The trigger is standard. Could a 'smith' have converted it to single action for a previous owner?

Thanks for the reply's.

Anything is possible it's just such an unusual modification, particularly on a gun like the Model 64. Why would anyone do that?

Even if the hammer is normal it's possible that a gunsmith removed the single action notch to make it DAO.

If it really is SAO I'd expect to pay a lot less than if it were stock.

Doesn't California require some revolvers to be converted to SAO for transfer? If it truly is SAO its not pricey or hard to convert it back.

Never knew that... that would make sense.

Kernel Crittenden, one of our local experts on SKU numbers and product codes, will likely be along to look into your product code.

I will defer to the good Kernel, but I have never heard of a PRODUCTION version of a SAO Model 64. Of course, the factory service department could, and would do almost everything if a customer asked nicely and paid for labor and parts.

And, before everyone jumps in, I said "almost everything." For example, I know that since at least the 1970s they typically would not cut and crown barrels to a different length (at least for most people - well known people, authors and such, yes, but not most people), nor would they refinish (back then) the Model 28 or certain other models (Airweights, maybe). Other than that, however, if it involved parts switching, and similar jobs, they were happy to do it.

Thus, my guess is that ASSUMING THIS WAS DONE AT THE FACTORY (and that is not a safe assumption), it was a one-off for a customer who sent in a standard Model 64.

The serial number puts it in 1998, according to the SCSW, and the product code relates to a 3" heavy barrel with a round butt. The code doesn't say anything about the action, but several other product codes show Double Action Only guns.

I can't think of one reason I'd want an M&P with single action only.

Betting he means "double action only".
I've never seen a fixed sight K frame SA only. Well, not intentionally anyway.

Product code 102504 is a plain Jane standard production 3-inch DA/SA Model 64. There's nothing special about it, or the CCY s/n.

Based on this, it's likely not a factory single action. Since if such an unusual gun were ever made for retail it would most certainly have it's own unique product code. Guns returned to S&W for aftermarket custom gunsmithing are another category.
