    I changed my g17 g5 sight to truglo tfx pro(i have another set on my sigp320 too And it work very well,so i know the way how to aim with tfx pro). But with my glock the group goes way to high. I aim for the bull eye but it went up ti 7 or 8 i shoot 10 round 10metre(see pics) then i assume it’was me so i took another stock 17 out and try it and the group is where it should be(pic 2).
    So i don't know what happens now
    Anyone experience this
    Thank you

    I had kinda same problems it was shooting real low so I called them and they are sending me another 0.016 higher rear site. They said 0.010 at 20 yards will bring it up 2.5 inchs and if true that will fix it.

    wrong rear height. You need to go higher.

    If I'm shooting to low a 0.016 higher sight will bring up the POI right ?
    Or am I wrong.

    Right. Higher rear raises POI

    Looks like you got sights for Gen 1-4.
    Sights for Gen 5 are a different height.
    If shooting high you need a taller front sight.
    Good Luck

    Generally if your shooting high you need a lower rear sight
    Each step down will equate to about 2" at 25 yards

    You need a shorter rear or higher front sight. Call Truglo with pertinent info like model and gen (those pics may help). They should fix you up.

    Thank you for every reply. I email them but they need the serial number on package that i didn't keep it, so my guess is to change the sight? Do they sell only the rear sight too?

    That is correct. I meant front sight because with Heinie's, Dawson's and Taran's you change the front sight for correction. In fact, Dawson offers a Perfect Impact Guarantee. If POI does not match POA, then you get another front sight for correction.

    Having the same brand sight on a different brand gun, or having the same brand sight on same brand gun does not mean they should behave similarly. You are lucky if they do.
    Models will vary.
    POA (sight picture) will vary depending on the model combination.
