Brand new C9 has bad barrel. Major tooling marks in bore. Bullets strike target 1 to 2 feet below POA @ 7 yards away. Most bullets do not hit my 18"x 24" target but hit randomly on the 4 foot x 4 foot backer. Tried 3 brands of ammunition. No difference. Greatly dissapointed. My .40 S/W Hi Point pistol and .40 S/W Hi Point carbine have been excellent. My .40 S/W Hi Point is actually more accurate than my .45 ACP Springfield XD.
Sounds like you got a bad egg that slipped through quality control....it happens, even with the higher dollar guns.
Since you bought it new I'd take it back to the dealer you bought it from, explain the problem and see if he's willing to replace it or refund your money. If not, you can send it to Hi Point and they'll make the necessary repairs
free of charge and most likely send you a free magazine/clip.
