Welcome. The PC4 is usually more readily available than PC9. I sold an unfired, complete PC4 about two years ago and it took me about three months to get a buyer. I let it go for 450.00. They are usually in the 400.00 to 500.00 range around here when they show up. I would watch the classifieds on this forum or post a "WTB" and see what's out there. I will keep an eye out for you at my two local gun shops and PM you if I find one. There are a few I've seen that were priced way too high, some 700.00 or so , some at gun shows, others on Gunbroker etc. I would just watch and wait for a reasonable price before I went that route. Good luck!
