Recently I picked up an Interarms PPk/s for a price i could not turn down. it has some holster wear and is blued, marked made in USA . I have not had the chance to fire it yet, it did not come with magazines. These should arrive from cheaper than dirt tomorrow. How can I find out when this pistol was made, is there a list online of serial numbers and approximate y ear of manufacture? What should I know about it? if it needs to be sent to the factory for reconditioning, to what factory do I send it? While in the garage tonight Dropped a cartridge in the chamber and attempted to lower the slide on it, and it did not want to go easily. the extractor did not catch the rim. should I expect that this will be a lot different when loading from a magazine. If it does need some work, are these very intricate pistols to work on, or should it be pretty easy to find a smith locally in nc, sc, or ga.
