I have two Glock factory G19 (15-round) mags, that I would like to trade for two Glock factory G17 (17-round) mags. These are not Gen-4 mags, so they will not fit a Gen-4 G19 if you have switched the mag release for left handed use. Or will sell both for $40.00 (OBO) cash FTF in the McMinnville area. I'll be glad to email photos (photobucket challenged). Thank you for your consideration. subman681 "Death from below"
