    Since Sig sights fit the XD, I think this information may be of use to us:

    http://www.praxagora.com/lunde/SigProFAQ/VI/2.html

    I'll include some of the info from that website here in case praxagora ever goes down.

    Rear Sight Heights:

    #4 = 5.24mm (0.21 inches)
    #5 = 5.52mm (0.22 inches)
    #6 = 5.80mm (0.23 inches)
    #7 = 6.07mm (0.24 inches)
    #8 = 6.35mm (0.25 inches)
    #9 = 6.62mm (0.26 inches)
    #10 = 6.90mm (0.27 inches)

    Front Sight Heights:

    #5 = 6.01mm (0.235 inches)
    #6 = 5.88mm (0.230 inches)
    #7 = 5.74mm (0.225 inches)
    #8 = 5.60mm (0.220 inches)
    #9 = 5.46mm (0.215 inches)
    #10 = 5.32mm (0.210 inches)


    A higher rear sight number (taller) will raise the point of impact, but a smaller front sight number (taller) will lower the point of impact.

    I called SA today; it took a few minutes to get an answer, but here it is. Apparently, the front sight post is .160", and the rear sight comes in three heights. Short is .258", standard is .260", and tall is .262". Hope this helps...I personally didn't understand what someone could do with the Sig sights without knowing the XD sights he or she had been shooting with.

    That's some great info on the sight heights. However, you didn't say what barrel length it went with. They must be different, my 3" XD right here and right now measures .167 on the front, and .205 on the rear. Not matching any of the numbers. :?: -Glimmer31

    Whoa...it's different by barrel length? I told the SA tech I had a service model (4")...could someone with calipers measure the heights on a 4" and compare?

    As I see it, the sight height has to be different by barrel length due to sight radius. At least that's correct by the gunsmithing books I have. -- Glimmer31

    I don't have a 4" to measure or I would. I would also be interested if someone with a 5" would measure and post the results. My 3" is an 9MM. I'll bet the 40s and the 45s are different too. Just a hypothisis. The guy who earlier said "they all shoot high" should know that Springfield sets their sights to the "6 oclock aim point" (at 25 yds, aim at a guy's belt buckel to hit him in the chest) type aim. I like what I'm hitting to set right on top of my front site. I think he does too. That's why they all seem to shoot high. He needs to lower his point of aim. -- Glimmer31

    I have yet to shoot the XD40 tactical that I just recieved yesterday, and I am seriously hoping the POA isn't at the 6 o clock position because that would just tear up my shooting style altogether, and just seems wrong all the way around.

    I installed a Williams firesight on the rear, but left the factory front sight, and since the new rear was just a tad bit taller, I'm hoping that will lower the muzzle up to the correct POA. If I'm shooting high, I can install the lower new sight to level it back out.

    If it still shoots high, I can get the measurement of the new rear, but does anyone know which sight SET to order to get a true sight picture out of it. After all, I just don't want to aim at a gut and wonder if I'm going to get a head shot or not. I don't want to second guess about shot placement. Or if someone could just tell me which set I would need to get and I'll scrap the Williams altogether after seeing if it's going to be accurate or not first.

    John A., I was just quoting my owners manual on my XD. I'm not sure what size target they used on the illustration in mine, but it explains the 6'oclock site picture as shoot at the 6'oclock position of the target and you should hit the bullseye. I don't care much for that either, I think it is an old policy of the military. I remember something like that in our instruction many, many, many, (oh hell, a long time..) years ago.....

    My 4" XD45 Compact has the following (as close as I could measure with my reloading dial calipers):
    Front: .223"
    Rear: .263"
    -this is from the top of the sight to the base of the dovetail cut in the slide.

    Which model Sig sights fit the XD, as there are different sig sights for different models from what I've seen?

    Is there an easy way to adjust the sights so point of aim and point of impact are the same at 25?
