Not quite understanding ....

....the adjustable rear sight on the ruger gp100 .357 magnum. Can someone explain how it should be set up?
Thanks

Here is the GP manual. Check pg 23. If that doesn't answer your questions then check back here.

Thank u....I read this already. But I'm still about 3 " low. Don't want to start messing with it.

What hold are you using as an aiming point and what is the load?

Light bullet loads usually have a lower POI than heavier/slower loads.

Turn the top screw counter-clockwise and raise the rear sight. That should raise your point of impact.

Is the front site factory ? I put a fiber optic on mine. Must 've been a little higher , had to readjust the elevation. But still had plenty of adjustment left. As some one else posted bullet weight will affect the elevation as well as specific powder loads. ( if u'r reloaden ) Perhaps try a factory 158 gr load , see where it prints. I believe the sights typically leave the factory set up for 158 gr loads. Or it is possable ... someone put the wrong front sight on it ... :roll: I'm not sure what height front sight shud be on it , perhaps the manual would say in the parts diagram. Good luck

regards , brushunter

Cube, are you saying you are 3" low after you have used up all the height adjustment? 3" low at what distance?

If you can't adjust the rear sight high enough, you have to lower the front sight by taking some off the top.
