The only way to be 100% sure is to measure your receiver extension
MIL CTR ID 1.14"
COM CTR ID 1.17"

I thought all S&Ws use a millspec tube?

In general if the threads are larger diameter than the rest of the tube it is millspec. If the threads are the same or cut into the tube it is commercial. But when in doubt measure.
