Dude....adjust the sights....you can't possibly expect a factory mass produced pistol to shoot the same groups at the same distance for all loads that will be encountered.
The adjustable sights on my tanfo are way to one side....why? because that's where my current load shoots....it's just the way it is.
If you really don't like it....learn to aim slightly to the other side or only shoot at 5 yards.
It's too bad you don't live close....I have a rear sight adjustment tool and have shoot thousands of rounds through my G34
