Help Drifting FNP Rear Sight

[m4shooter]

Has anyone drifted their FNP sights? My FNP-9 is shooting great groups, but they are all left of center. I would consider this a technique problem, but I do not shoot left of center with my other handguns.

So I am considering drifting the rear sight, but I have never done this before.

Can anyone give some drifting pointers to the novice who doesn't want to bang up his sights too much?

think wooden dowels and "light" taps....

Drifting rear sight

Don't know if it will help or not but the attached pictures show what I did to correct the front sight on a Sig P239. Just had to shift it a hair since it was off to the right about 5" @ 20 yds.

Thank you everyone for the responses. This does give me a much better idea of what to do.
