For sale are a bunch of generic brand (not Glock brand) Glock 17 pre ban mags. These are still brand new and have never been used. These have been tucked away for 25+ years. They will fit the G17, G18, G19, and G26 as well as carbines that take Glock mags. 

Price is $25 each or 5/$100. Get them while they last. 

I can meet locally in framingham or on the North shore near my work. If shipping is preferred I can do that too but I’ll need a pic of your LTC and you would have to cover shipping costs.
