They are 12 Round Magazines .40 S&W.
Forgot I had these.(Had an M40 back in the day)
2 of 3 had some very slight/minor discoloration, and very minor surface corrosion pitting. I buffed it all out re-blacked, and buffed with CLP. (They were in storage for a long time).
Followers and springs also in great shape.
I disassembled mags, cleaned and buffed springs with CLP. 2 of 3 Appearance is not perfect, but they are solid, functional mags.
I build ARs, Pistol practice at range 2-3x a week for 20 years. I would not sell ANYTHING I wasn't 100% confident in using myself. I can send pics of before and after if you like.
