You may want to see if you can drum up another group buy. Metalform mags are of good quality, and they have proven to be reliable. Also, check the for sale board, I am pretty sure TroyFD403 has some NIB for sale.
I have NIB Metalform 45-797W for $35/twin pack including shipping and handling. 45-797W is a 7-round Magazine with round follower and Wolff Spring for goverment model. If you are interested please let me know by PM.
I have purchased several of Metalforms 7 round S.S. #45-797 magazines, with the welded base, round followers. Yesterday, I ran 250 rounds thru them in my new Kimber .45 at the local range. I'm very pleased with them.
