The magazine bodies I got from Numrich were a little grody looking so they're spending sometime in the tumbler. 
The catch plates are the correct ones.

Who is GPC?
It's not "scalping" it's supply and demand. The 10xx are seeing a resurgence in popularity, but S&W doesn't make magazines for it any longer.
People who have them are asking what the market will bear. People can buy, not buy, or hope that something like this comes along so they can build their own for less than the market is for complete magazines.
I'll go on record as saying that I haven't seen a genuine S&W pistol magazine body crack or outwardly fail in my life.I have 3 spare 1006 magazines on hand now. Has anyone seen a magazine tube fail (crack) through regular use? If not I will just stay with the 3 extra magazines I have. If they do fail I will buy at least one replacement tube.
