    I've got a G17-5 with stock plastic sights and want to install night sights. My local shop has got the Mepros in stock but they appear to be just a hair taller than my plastic ones. Didn't have calipers with me to measure and haven't been able to locate the actual specs on the Mepros.

    Question is, will POI remain same as factory sights or will it be higher? My use is for short range, 25yd or less.

    Inquiring mind wants to know...

    What elevation is shown on your installed GMS sights? Usually you'll see a "6.1" or "6.5" in the rear sight notch, which is the total sight height in mm bottom to top. (Subtract 2mm to determine how tall your installed rear sight is above the top of slide. Standard OEM front sight height is 4.1mm above top of slide.)

    I haven't checked out Meprolight's product line in several years, but it once offered two different rear sight elevations for Glocks...one equivalent to 6.5mm and the other equivalent to 6.9mm.

    If your Gen5 rear sight is 6.1mm, that slightly taller Mepro rear sight is likely 6.5mm. An old Glock very approximate thumb rule says that would raise the POI about 2 inches at 25 yards.

    Ive put Meprolights (Glock 9mm) on a most of my Glocks, including a couple of Gen 5's, and they have all been right on for elevation.

    I am very much a novice when it comes to sight heights. I have been using XS Big Dots for the last 7 years. And have decent muscle memory of where to aim them!

    Any specific manufacturer of sights makes multiple models, each in multiple elevations of either rear or front sights. Further, POI vs. POA depends on the sight picture used by the shooter, the range to target, and the ballistics of the specific cartridge being fired.

    Simply declaring "I put ACME sights on my gun and they're always right on" is pure nonsense and absolutely worthless disinformation.

    Meprolight lists their Glock sights by caliber, and some specific models. I havent seen them offer sights of different "heights", at least for the Glocks.

    Ive found the Mepro 9mm sights Ive installed, regardless of the model listed, seem to all be on for POA/POI.

    From what I understand, Gen5 requires different height sight combos than other Gens of same model. YMMV

    As long as the relationship between the front and rear remains the same, whats it matter what the height is?

    Ive put Mepros on both a Gen 5 17 and 19 (same model numbers) and they both shoot POA/POI.

    As already said, given the same eyes, point-of-aim, distance and ammo used, so long as the front/rear sights are properly regulated for each other(ie; they're a set), the actual height of the front/rear sights is not relevant. The POI should be the same.

    For example, for one of my G19, I replaced a set of Trijicon sights with Ameriglo I-Dot. The I-Dot is much taller but because I replaced the I-Dot as a pair, POI remained the same.

    My excuse to post gratuitous Glock porn...
