I have a P10C with 2 19-round mags that fit flush the P10F. Would like the 15 rounders with the plus 2 base plate but will be contempt with regular 15 rounders as well. The mags for trade have been loaded (doesn't affect spring wear) and sat in a ammo box in a temp controlled room, never been fired and are essentially brand new I'd expect the same if we did proceed with a trade. Text me 817 706 2944 for pics.
