[P-11 shooter]

Just installed a set of Warren Tactical fiber optic sights on the M&P. The sights are clean, and crisp and when I shot it the first time I got the tightest group I've had with my pistol.


But not at point of aim. At a distance of about 15' it was hitting about an 1" low and about 2" to the left. The old sights were dead nuts.

I know they're centered to the slide because I used a dial caliper. I took it home and made a fine pencil mark and drifted the front sight a little bit. The gun is now hitting closer to center but still low. If I move it any more it will be clearly off center. I don't think it's my shooting because it was dead on before the sight swap, and I'm shooting really tight, consistent groups.

What now? I like the sights, but I like my guns to hit what they're aiming at. They're fixed sights so I think I'm fucked on the elevation anyway, but what should I do?
