question about sighting in a S&W 1911

[John G C 1]

I have a S&W 1911 with target sights. The gun is sighted in to what I think is called a 6:00 setting. When the front blade is properly aligned in the rear sight, I make the very bottom of a three inch red circle sit just touching the top of the front blade and at 15 yards the round goes right into the center of the red circle, which is one and 1/2 inches up from the bottom.

At least it does that when I do my part.

Two questions:

Any reason not to change this sight into a POA-POI sight?

If I do so, I know I need to lower the point of impact by lowering the rear sight. Does anyone have a guess off hand as to how many clicks it would take to lower the sight one and 1/2 inches?

Thanks for the thoughts and comments. I have only been shooting this gun for three months and have about 600 rounds through it. I think it is mostly broken in. Shoots great, and part of me does not want to mess with a good thing. But POA-POI would make it easier to shoot at red bullseye circles of different sizes. Strictly a range gun.

You will raise rear sight to change poi up. Several factors can also change it. Are you shooting 230 grain ammo. Light loads hit lower. As far as clicks, that will also change with distance to target. At 25 yards, I would guess 6 would be close. Just remember how many you moved it, and you can always go back. I personally like the bullet to hit just above front sight. That way I do not cover target, but instead, dot the "I".

6 oclock or center hold

I think the difference in how you set up the sights is dependent on the type of shooting you do. If you punch paper and score the hits, the 6 o'clock hold probably allows a more consistent sight picture for accuracy. If you are shooting a more action style, say metal targets at different distances against a clock or are mostly a plinker, then the center hold allows for a quicker target acquisition.
