I just got a sig239 with sig nite sights.I never shot a sig but it appears to shoot low.The front sight has to be at the top of the black to get it in the black.If aimed at the bottom of the black at 30 feet it is 5 inches low.Now I do understand that it could be me broken but the gun seems easy enough to shoot.It doesnt matter if its on the double or single action too.Just wondering if anyone has ideas, thanks
