Bought my first HK this week!! Love it. P30 9mm. Stopped back in looking at other hk's and saw an old, kind of rough looking p9s in old box. It is black, black grips and priced at $550. So my question is: what are some things to consider when looking at this model? Is it a good price? Should I buy this one, it was a long way from new. But I've read some great reviews on this model and after my first HK purchase I'm just jonesing for my next one. Thx for your help everyone.
