Hey Guys, I have a HK45c and have been very happy with it. Like most of you, I have many guns and they are all in nice condition. My Hk45c has Trijicon sights installed for carry reasons. Today I went to the range and the gun was shooting at least 7 inches low at 10 yards. I get home and check everything, and all is good. I bore sighted the gun and it is dead on the money. While I am no Navy Seal, I was perfect today with the couple others I took, so It has to be the gun. I did try two different types of ammo also. Any ideas or help? Thanks in advance.
