    I have installed a set of Classic Heinie sights (#320) on a G17L and a set of SlantPro 3D tritium sights (#319) on a G17. Both pistols shoot too high. They both shoot ~15-18" high at 50yds and several feet+ high at 75yds with 115gn bullets. Both have stock barrels and shot spot-on with the factory sights and the Meprolight and Trijicon sights that were installed prior to installing these Heinie sight sets. Any thoughts?

    Yes I contacted them through their website.

    It will chap my hide to no end if they tell me to buy another not-cheap front sight after I purchased their not-cheap sight "sets" marketed as being for the exact gun onto which I installed them.

    Which front sight do you have? They make two.
    On my 17L they shot about 12" high at 25 yards. I stoned about .020" (IIRC) off the rear sight and re-blued with a blueing touch up pen.

    G17L Traditional set has: Ft= 0.215" Rr= ~0.265" (difficult to measure due to the angles)
    G17 SlantPro 3D set has: Ft = 0.215" Rr = ~0.265" (again, difficult to measure due to angles)

    It really annoys me that the myriad sets of Meprolight, Trijicon, Ameriglo, Truglo, HiViz and factory sights I have, all also sold or installed as sets, are spot-on. But these very expensive, arguably the most expensive brand, sights sold as a set are not anywhere close to being spot-on.

    You need the .250" front. I see that the .215" is listed as the standard Glock front, should be .250". I see they now also list a .235"
    You can calculate the height needed by the amount it shoots high and your sight radius. They might swap you a new front. Try calling them.
