I recently got a 10-7, and Roy dated it as shipped Jan. 1979.

So I'm looking at my Standard Catalog, 3rd edition, page 174, where it shows the model dash number engineering / production changes, by year. It says:

"10-7 (1977) Gas ring change from yoke to cylinder on tapered barrel.

10-8 (1977) Gas ring change from yoke to cylinder on heavy barrel model."

So I'm wondering if my 10-7 could have been made in '77, and sat in stock at the factory for a year or two before being shipped in Jan 1979? Did S&W do this? Or possibly a typo in the book concerning the "10-8 (1977)" ?

Otherwise, it seems that my 10-7 should have been a 10-8, according to the time line. Has anyone else noticed this situation?

The 10-8 is a heavy barrel model 10. I believe the 10-7 continued until 1988. I assume yours hase a standard barrel.

S&W did not ship in serial number order; your gun may very well have been at the back of the stack and not shipped until a couple years after it was made. Plenty of examples posted here in the past of guns with close serial numbers which were shipped years or a decade or so apart.

Many models have had more than one "dash" (engineering change) produced at the same time instead of the later number replacing the earlier one. The model 10-7 and -8 is one example; the 36 is a 2" and the 36-1 the 3", and both versions were being made during the same period.

It's easy to get confused. Usually, one dash number replaces the previous dash number. That is, production of the earlier one ends.

However, there were times that both dash numbers remained in production simultaneously. The M10-5 and M10-6 are an example of this. The -5 had the standard barrel while the -6 had a heavy barrel. Apparently, each barrel was popular enough to keep both in production. The M10-7 replaced the M10-5, while the M10-8 replaced the M10-6.
