My former 1006 with fixed sights couldn't be "persuaded" for love nor money....
It had a hex or Allen head screw that apparently had been stripped out.
Fortunately, it shot dead on -- and didn't need any adjustment... But I was trying to put night sights on it...No go -- and at the time, I didn't know a half-decent Smith 'smith. So it got away from me in a tight spot...
I've been trying to get that pistol back for two years now...
But it is drift adjustable...
Still, let me suggest something, if I may.
Before you go trying to move it -- unless you're a trained expert pistoleer -- your point of impact might be drifting left or right because you're pulling the shot.
Most Smith 10s I've ever fired with Novak sights were consistently set to point of dead aim at 25-35 yards.
Others haven't had that experience with adjustable sights, but Novaks from the factory seemed to have absolutely brilliant consistency with any ammo I shot at that range.
I could group into the K-5 zone out to 50 yards with any ammo I fired -- including "FBI loads".
I still haven't figured out how S&W ever achieved such a great, near-perfect compromise that intersected so many loads.
If I were you, I'd definitely try to find a good shooting instructor to check your firing form and some of your practice targets before you move that screw.
