Fiber Optic Some Glock slides are thinner at the front sight hole, and the sight's mounting post may protrude. This causes the set screw to tighten against the sight instead of the slide. To correct this, file some material off the bottom of the post (indicated in silver) so that the post sits below flush.

$45.50 - $49.95

Precision CNC machined from hardened 4140 tool steel and finished in black QPQ salt bath nitrocarburizing (aka Melonite, same as the Glock slide).

  • Fits: ALL Glock models, all calibers, all frame sizes, all slide sizes.
    • Fiber optic (.060" rod with .075" diameter counterbore on 40lpi serrated blade face for flared bulb).
    • Compatible with .250" blade height rear sights.  NOT compatible with Glock factory rear sights, fixed or adjustable, as they are shorter than .250" blade height.
  • Height: .215", .235" and .250"
    • ALL Glock models, regardless of size, caliber, or generation, most commonly use the .215" front.
    • Glock 34/35, 41, 17L, 24L most commonly uses the .235" front. Sights do not overhang slide cutout.
    • Glock 48 uses .250" front with our Glock MOS Standard Height Rear Sight.
    • The .235" front lowers impact approximately 2-3" at 25 yards relative to the .215" front.
    • The .250" front lowers impact approximately 3-5" at 25 yards relative to the .215" front.
    • Please note that different guns will vary in regards to point of impact, especially with differing shooter preference. These heights are recommendations, and we cannot guarantee point of impact due to variations in individual guns. Point of impact will vary by *individual gun* and not so much by generation.
  • Width: .125", .115"
    • Blade width is strictly personal preference.  Thinner fronts cover less of the target area and are preferred for speed.  Thicker blades like the .125" are preferred for improved accuracy and are our most popular.

All sights include set screw and one section each of red and green .060" fiber optic rods.

**INSTALL ONLY TO MAX TORQUE OF 6 INCH/LBS or else you may risk cracking the threaded post.

***Due to manufacturing tolerances by our fiber optic supplier, there may be slight variation in the diameter of the fiber optic rod. Use a razor blade or X-Acto knife at 90 degrees to the rod and gently scrape the outside diameter a little bit and it will fit right in without any compromise to the function.

    Yellow Night/ Day Front Sight

    This is my second Yellow Night/Day Front sight that I have purchased from 10-8. The first was a .215 for my Gen 5 Glock 17 MOS. This sight was a .235 for my Gen 5 Glock 34 MOS. I have 10-8 sights on all my glocks including tritium front sights, fiber optic front sights and a brass pin front sight one a G19. So far, I the Night/Day sights are my favorite. Quick and easy to pickup in all light conditions.

    Glock front sight

    Installs easily, looking forward to taking my G20 to the range to confirm zero. Looks good with the new rear sight as well.

    Best sight, no question

    I only run 10-8 sights on all my pistols. Best out there IMO.

    New Front Sight, same Awesome Quality

    I have 10-8 fiber optic, tritium and brass bead front sights on all my glocks. Decided to try the Night/Day front sight on my G17.5 MOS. So far I am really liking it. Good visibility during the day and nice and bright in the dark. I went with the standard .215 height as I do with all my glock 19's and 17's. I do not worry about distances when I shoot. I adjust my POA, these sights work great.

    Preferred .235 height with the MOS rear sight

    I found that I preferred the .235 height for my Glock Gen5 19 MOS and Glock Gen5 45 MOS, as well as a Glock 48, with the 10-8 Glock MOS rear sight. I tried the recommended .250 height sights and I found that for my ‘point of aim’ (at 10yds) they I shot too low. The .235 worked perfectly for me and I bought a set for each Glock.

    Perfection!

    The fiber opt front sight combined with the U notch rear sight is the perfect set up for my new G 17 Gen 5 duty pistol. The fiber optic front is fast to pick up and easy to see in all conditions.

    MOS/Front Sight Combo on Glock 48

    Looking for a set of sights for my Glock 48. It will be my primary off-duty carry gun and I was quite happy with the 10-8 sights I use on my Glock 35. There is some issue about what sights will have the correct impact (elevation) as a lot of people are using sights for the 42/43. 10-8 specifically recommends the MOS and front sight combos as addressing the longer sight radius of the 48. The install was a snap, rear sight was snug but easily installed with a derlin punch. Sight picture is excellent. Very happy and will continue to use 10-8 sights when buying Glocks and replacing the plastic sights.

    Bright fiber optic makes a world of difference!

    Night and day difference between the fiber optic and its stock counterpart. The front sight is a breeze to pick up. My slow fire accuracy improved noticeably. Drawing from concealment and breaking the first shot was also much easier to do with the 10-8 fiber optic front sight. Its the best I’ve used and wouldn’t choose anything else.

    .250”h for G19Gen5

    By far one of the best Fiber Optic sights on the market. There is a recess to keep the rear bulb shielded, so you get a clear crisp sight picture, without the fiber optic obscuring the overall shape of the sight. The FO rod is well guarded with a shield in the middle, and the U-Notch rear makes for very fast and intuitive shooting. Be sure to use the .250h front for Gen5’s and you’ll have POA/POI at 25yds and closer.

    Easy install and do what they’re made to do.

    I wanted a more POA/POI shot placement and opted for the .250 front sight with the already installed rear sights. Easy to follow tutorial for installing the sight and fiber optic. So far great product. Thanks!
