I would like to put together some spare parts for my P3AT to have on hand. I know I can always count on Kel-Tec warranty if something breaks but that's not what I'm talking about. I want to have enough parts on hand where I can fix any eventualities. (I've posted a similiar thread in the Sub200 section) So...What P3AT parts are most likely to wear out and need replaced? I know some recoil springs and some ejector blocks are good to have on hand. What else? What about keeping it operational long term. One of each spring? or is that uncalled for?
