I wouldn't worry about finding parts for the P6. Just after a quick look at www.gunbroker.com, there are mags available (although a little pricey at about $50each). I have wanted to get my hands on a P6. There are plenty of people who have gotten the police guns with some holster wear, but they were very mechanically sound. I personally wouldn't hesitate to purchase a P6. I say, if it feels good in your hands (if you can get a hold of one), then go for it. I don't know about the P239, so I can't make a comparison, but if it were me, I personally wouldn't look any further than the P6. Others who may have experience with both should chime in though. Good luck!
