Hey guys, I'm relatively new to the buying and selling process and I've got a few questions. I've found a used Kahr K9 (black finish with night sights) for about 600 which seems to be a good deal based on the prices I see on gunbroker and the factory msrp. I'm wondering if there is an online resource that will allow me to check the age of this particular gun. Also any pointers on how to make sure I'm getting a quality deal here would be much appreciated. Thanks for your wisdom.
