I have no idea were I aquired this magazine from. I've never had or shot a P40 much less remember even seeing one. Anyway I have one 9 round factory mag for a Kel-tec P40. They are going for about $25 bucks online from my research to figure out what it was. It's in excellent condition with a strong spring. Made in Italy by Mec Gar. Free to anyone who needs or wants it. Meet me in Killeen or I can ship, but I'm not looking to go out of my way or spend money to give it away. So if you want it pm me and we can arrange something.
