Another trip to the range and so far around 1000 rounds with not one problem. Did some close up shooting and came to the conclusion that my sights are definately off. If I shoot POA all the shots are low. With my sights lined up on bullseye at 5 yrds I'm hitting about 2 inches low. If I put my front site a little above the rear I can hit dead on. Any remedy to this besides new sights? I planned on getting some truglo TFO's soon so hopefully that will solve the problem. At 15 yrds this really affects my groupings having to overcompensate for the sights.
