My father and I both own P228's. He has a factory P226 mag that he got from Sig with a much larger base plate to accomodate bigger fingers or whatnot. My factory mags are 13Rd with the normal base plate. My question is this: Where can I find these P226 mags with the large base plates? I have searched everywhere I can think of online but to no avail. I dont even care for the larger capacity, I would settle for just finding the base plate to put onto one or both of my mags. Thanks for any help.
