I feel for ya, ARB.
My P229 Sig came from the factory like that....
.... but in my case, it shot way off right of center. (like 6in.+ @ 25yds.
) When I put a bore-sighting laser in the bbl., sure enough..... it was off.
The problem w/ fixed sights is; I need a special sight press to move it (a cheap
Sig press costs $120!) or must take the slide to a gunsmith.
Be thankful that your C/C doesn't have a problem & is dead-nuts
