22/45 Target sight adjustment

The manual does not seem to give you any formula for clicks/windage on its sights. Can someone tell me at 25 yards if I just want to bring my POI left just 1.5 ", how many clicks counter clockwise should I move the adjusment screw. Thanks.

I just shoot a group, adjust; shoot a group, adjust; etc. you can over think it. You're not talking about adjusting a sniper rifle at 500 yards.

Seems like every couple of months I have to post this picture I made for adjusting the Mark I/II/III rear sights.

I have a laminated card like this in my range bag with Ruger adjustments. Or other firearms I take to the range with adjustable sights. Of course that's because my memory isn't so good anymore.

I've never understood why anyone needed a pistol when after owning rifles for 50 years seemed sufficient, but I succumbed to a wish to owning a Mark type pistol, which I've had since 'Nam. I bought a Mark III Hunter this last week, a first in for me where pistols are concerned, and immediately ordered a lot of upgrade parts, just as I always have done with my rifles.
To the point of this thread, the Mark III has the rear sight offset almost a quarter inch to the right, from the factory. I intended to get the parts, including scope- lapping ect ( vision isn't anything like it used to be, lol) done, before really dealing with the weapon but after noticing the terrible sight alignment from the factory, is it possible I will never be able to get this barrel and scoping lined up on a usable plane?

Truthfully, I've never encountered this where the factory sights were so offset since purchasing a rifle made from back in the 50's and it never was capable for any real fine tuning,

I'm wondering if that 'almost 1/4 inch' makes the pistol no better for sighting?

Sometimes the rear sights come loose in the dovetails and move to one side of the receiver or the other. There is a hold-down screw located in the top of the rear sight that you can loosed and move the sight back toward the center of the slot.



The hold-down screw is the small slotted screw on the left side of the sight base. Once you move the sight be sure to apply some blue Locktite sealant to the screw to prevent it from loosening again later.

Bullseye - Thanks, The pistol had me fooled, I, after removing hold-down screw and penetrating oil the base, I literally had to beat the tar outa the base to move it. I'd figured a mod not shown where the base was no longer moveable was the situation and at 20yrds, windage wouldn't even compensate enough.
Would think the factory would have spec'ed the rear sight better than being 1/4 inch off barrel center before releasing for shipping.

Anyway, benchs' so the sight is on center now. Thanks for the response, can't wait for lapping to get done and see what a scope will do.

Keep in mind the 1/2" at 25 yard adjustment
becomes : 1" @ 50, 1 1/2" @75 and 2"@ 100
Most people know this but I though I would mention it for the few that do not.

Nice picture Bullseye ... yet I like JWoodard's idea ... shoot adjust and shoot and adjust again .... that way you can get some shooting time in and have some fun with you pistol.
