I've got 4 Marvel 1911 .22LR Conversion magazines to sell with 10 metal basepads bought from Marvel and 1 Metalform rubber basepad, and magazine loader. One magazine needed a slight tweak to the lips, but all ran fine in my Unit 1 with Federal load 750. It's possible that the feed lips may need tweaking to get it to work with different ammo or your upper. The metal basepads are pretty much new, as they only went to the range with me once or twice. There are 5 mags in the pictures, but only 4 are for sale. Marvel sells these mags for $58 each. I am asking $35 per magazine with basepad or $150 for the whole lot.
