Glock Front Sight (all styles)

  • Fiber Optic
  • Night/Day, Orange
  • Night/Day, Yellow
  • Brass Bead
  • 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.

Product Description

Finished in black QPQ salt bath nitrocarburizing (aka Melonite, same as the Glock slide).

  • Available in:
    • Fiber optic (.060" rod with .075" diameter on 40lpi serrated blade face).  Fiber optic comes with 1 each red and green fiber rods.
    • Night/Day - smooth face with .078" Night Fision green tritium insert with .094" Orange or Yellow polymer ring.
    • Brass bead insert, .075" with polished domed face, serrated blade face.
  • Fits: ALL Glock models, all calibers, all frame sizes, all slide sizes, except 42. 
    • NOT FOR THE Glock 42, which is the only model with a unique slide, and we have specific sights for those. 
    • 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.
  • 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.

**Our front sight posts are made to maximum dimensions for a tight fit in your slide.  However, due to extremely wide variation in the mounting holes in the Glock slides, our posts are sometimes oversized.  If a gentle tap with a nonmarring hammer does not seat the sight, file just a little off the outside with a diamond hone and try again.  


Read our article about sight selection.


Please contact us for a discounted price on additional front sights if your initial purchase does not provide the desired point of impact.

  1. MOS/Front Sight Combo on Glock 48 5 Star Review

    Posted by on 26th Sep 2019

    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.

  2. Bright fiber optic makes a world of difference! 5 Star Review

    Posted by on 2nd Jul 2019

    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.

  3. .250”h for G19Gen5 5 Star Review

    Posted by on 28th May 2019

    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.

  4. Easy install and do what they’re made to do. 5 Star Review

    Posted by on 15th May 2019

    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!

  5. Warning: 0.215" isn't right for G45 3 Star Review

    Posted by on 4th Apr 2019

    Contrary to the advice in the description advising a 0.215" front (and this is noted in a caveat about Gen 5 so it's not entirely a surprise) my G45 with the 0.250" rear sight impacts ~2.0-2.5" high at ~10 yards which turns out to suggest a ~0.250" height front would have been appropriate.

    As for the sight, it's pretty good quality. The fiber is a bit larger than I'd like, but that's subjective. It definitely seems durable.

  7. High Quality Sight 5 Star Review

    Perfect fit. Great pairing with the U notch rear sight.

  8. High Quality Sight 5 Star Review

    Posted by on 5th Sep 2018

    With the green rod insert and paired with the .156" U notch rear sight, this fiber optic front sight is just right for me on my G19.

  9. awesome 5 Star Review

    Posted by on 18th Aug 2018

    I put the .215 fiber optic on my Glock 21 along with the MOS standard height rear sight for deer hunting. The visibility and target acquisition is fantastic. I'll never put another brand of sight on my pistols again.
