Don't know if this good anymore, but I used to go to Springfield Sporters, located in Penn Runn, PA. They used to be one of the top suppliers of Enfield parts, including magazines. I have done business with them a few years back and was always happy with the service. However I have heard or read that they sold a lot of their Enfield parts to Gun Parts. SARCO is pretty good as well, but they have been getting hi in prices. Good Luck...........
