Up for sale a three brand new, but out of their boxes, Ruger 10 round factory magazines for the MK IV 22/45 pistols. I do not believe that these will work in older 22/45 pistols as the part numbers for the MK IV 22/45 mags & MK III 22/45 mags are different. $85.00 for all three shipped via priority mail. PayPal or US Postal money order, please.
