Hello fellow HK owners. This is my first post and I just bought a VP9 a little over a week ago. Wooh! I felt the gun and just fell in love. Although I'm having some issues with POA/POI. I have been shooting guns my whole life. Mostly glocks and S&W. I own a glock, sig, s&w and some milsurp pistols. Never had an issue with any pistols as far as being pretty accurate at just about any distance. Especially 7-10 yards. Always grouped nicely. I was trained by my step dad who has been a LEO for 25 years now. I've also been trained by military veterans and swat members etc. So needless to say I was taught properly. Today I finally got to shoot the VP9 at the range and was shooting at 7-10 yards and shot over 200 rounds. I was shooting very low. So I changed grip and started shooting left/right depending on how I was changing so I finally said screw it and went back to my natural grip and started aiming high. Then it was hitting where I wanted it to. I always have aimed like "sight picture 3" so that's how I was aiming this one. But I was getting great groups just very low. So when I aimed anywhere from 2-4 inches high I started hitting where I wanted to. And no it wasn't just me pulling the shot because I rested my arms and the gun on the bench and it still shot 2-3 inches low. This is with factory blazer brass ammo so no issues there. The model I bought has the Mepro night sights and are supposedly the same height as the other factory sights. So without further ado has anyone else had this issue or are my sights possibly defective and or not seated properly?? I contacted HK customer service but have not heard back yet. I am really dreading having to send my newest edition to the collection in for service already. But hopefully if I do it was just a small manufacturer defect that can be fixed. Because I really love the gun. And don't get me wrong I tore the target up with great groups. All kill shots. They were just 2-4 inches lower than POA using sight picture 3. And it wasn't just because I was "off" or something today because I pulled out my glock 30 and tore the face out of the target. Any input would be much appreciated. Thanks!!
