Road King Larry:
I never thought much of that wheel of misery. If one obtains consistent off-center groups, one should correct the sights to compensate. Both my son and I are well-versed in consistent holding and sight picturing, etc, and are not bad shots at all. We all know that every gun is a rule unto itself, and that sighting corrections are frequently necessary even when changing from one shooter to the other, so it's necessary in this case to adjust the sights, not to correct any deficiencies in the shooter(s).
lee n. field:
It doesn't matter "what gun," simply that autos in general with dovetailed fixed sights need to have the sights moved for us. Maybe it's something genetic with our particular eyeballs. However, FYI, this is true in several cases with 1911s, and in particular in this case, a Kahr CW9. I have noted the same problem with Patridge-style sights in my rifles as well over the years. Out-of-the-box, I always have to crank the windage a little to move the group to the right. (I didn't ask my son if he noticed it with rifles as well.)
Cliffh:
I was thinking of drilling and tapping a large NF hole in a 1/4" steel plate and (with cushioning) mounting the plate and slide in a hefty vise, then pushing the sight over with a screw. The advantage here is the precision with which the sight could be moved, just based on the screw pitch, but "drifting" it over seems to be the simplest solution.
So it would still be helpful to know whether they're cemented in, or shrunk in, or are just a wringing fit, or if I just need a bigger hammer or some dry ice, or what (see OP).
