I was an early adopter. Got mine about a week after they were released, most of that time being the idiotic 3 day wait I had to endure in Illinois. It's become my go to full size pistol for classes. It's never failed in any way. I had my old smith put Trijicon HD sights on it to replace the original luminescent ones. Carry it in a JM Custom Kydex OWB holster that fits up tight to the body and hides under a sport coat or winter coat (in Chicago we had real winter).
After I got mine I took my wife out shooting and she wanted to try it. (As an aside, my wife is the girl who goes to the gun store and buys the gun she thinks looks cool. She's come home with an HK USP compact and a Beretta PX4 that I had nothing to do with.) She decided after one magazine that she was going to take my VP9 and give me one of her other guns in trade. I really like the USP of hers. I flatly told her no, go buy your own. And she did. Went to the smith and had Trijicon HD sights put on hers too. She's also rocking a JM Custom Kydex OWB, but she only wears it at the range/class.
