    A while back I put a Dawson adjustable sight set on my 1911 (as in I did so, no "Professionals" involved). after adjusting for elevation, the rear sight looks a little high to me... :eek:

    Best pic I could manage tonight using the camera in my phone.

    So am I right in that this is an abnormally high adjustment to zero the gun? or is this actually normal for this sight style?
    And if it is too high, what corrective action to take? (shorter front sight right?)

    as always, thanks in advance for any info or advise. :)

    How tall is the front sight on that thing? You will need a shorter front sight

    Did it hit ok with the original sights? How tall are they?

    Yes, and I can't be sure since the original front sight got dropped into a parts bin with a couple of other random sights about a month before I ordered the new set (was going to be a frame up rebuild, changed my mind)

    Post the Dawson part number for the rear sight if you don't mind.

    *Edit* ...or maybe the link @Catfish posted is the only one like that.

    Well measure your old rear sight. Was probably
    .325” or maybe .375”. Old front was probably .180 or so.

    I think every .007” in sight change is about an inch at 20 yards. Even just putting the 190 front on with the original rear should only make an inch difference.

    Something seems off.

    ETA: that rear looks adjusted way high. To lower it down to a normal height it looks like you would end up with an unusually short front sight.

    sent the pic from the OP to Dawson earlier today and their response indicates that they think it's sitting too high.
    btw, if the sight you posted a pic of were installed the, "blade" portion would be half as far away or less from the top of the slide as mine is. notice how much of the dovetail foot is in the slide in my original picture. Yeah my sight is sitting much higher than it should. it should sit at about one full turn off dead bottom, not nearly 2-2 1/2.

    It is,

    Well, I just followed the first part of the instructions i received in reply from Dawson, looks like this may come down to me bing inexpereinced with the sight type, and a worry wart.
    the "baseline sight setting" they wanted me to use, turns out to be exactly where the sight is set in the picture at top.

    unless i get another email back from them to the effect of "That doesn't sound right" i'm just going to let it go and get on with shooting

    Have received a further response on this from Dawson. figured i'd share.

    If you don't like the way the sight looks when it is 12 clicks up from the bottom, adjust it back down 6 clicks and re-shoot the pistol. Let us know how far off it is shooting and the distance to the target. Wether the sight is one turn or 1/2 turn up from the bottom of the travel is personal preference. The full turn of the screw just gives you more adjustment if your point of impact changes due to ammo changes.

    So I think for now i'll leave things as is and maybe at a later date adjust down 6 clicks and resight.
