15 rd. factory Smith & Wesson magazines that fit the P-11. These are in excellent condition, have stiffer springs installed , tested & fully functional in my P-11. Almost ALL S & W mags will need to have stronger springs put into them to function in a P-11.. These are ready to shoot !! I will sell these for $30 each, or 2-$55 , which will include shipping. That's a 50% increase in capacity for these little pistols ! If interested , let me know.
