Ebay is the best source for original factory 8 round mags with the S&W 9mm marked metal base plates.

The ones with metal followers are a bit more elusive than those with black plastic followers.

I've purchased 7 original 8rd mags off ebay in the $20~$30 range in like new condition to ones with some worn off bluing.Three had metal followers.They all work well in my 39-2.

I have only one original factory Model 59 14rd mag with a metal follower.
