Glock Front Sight (all styles)

  • Image 1
  • Image 2
  • 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

All of our front sights feature 40lpi serrations to provide crisp visual focus and glare reduction.  Finished in black QPQ salt bath nitrocarburizing (aka Melonite, same as the Glock slide).

  • Available in:
    • Tritium insert, .075" green with silver vial, no white outline
    • Brass bead insert, .075" with polished domed face (AVAILABLE IN SPECIAL RUN SECTION)
    • Fiber optic (.060" rod with .075" diameter on blade face).  Fiber optic comes with 1 each red and green fiber rods.
  • Fits: ALL Glock models, all calibers, all frame sizes, all slide sizes, except 42/43. 
    • NOT FOR THE Glock 42/43, which is the only model with a unique slide, and we have specific sights for them. 
    • 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.
      • **We are still compiling data for the Gen5 Glocks, but if they are like any of the other generations, there may not be a 100% consistent trend across all of them.
    • 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.

  1. fast pich up 5 Star Review

    Posted by on 10th May 2017

    I received the site on Saturday afternoon. I installed it and shot a competition on Sunday. The site was great! Fast to pick up, and easy to see. It comes with enough rod to try each color 2x or more if you are not sure what will work best for you. So simple to install and a great fit!!

  2. Fiber Optic Fronts 5 Star Review

    Posted by on 14th Apr 2017

    This is my 2nd Set of 10-8 sights. I run these on my G19 and G34. Hands down they are the best. Nothing else compares. Simply Quality!!

  3. Best sight ever! 5 Star Review

    Posted by on 13th Apr 2017

    This is the fourth 10-8 sight i've ordered. They are the best sight picture of any fiber optic sight I've seen. I shoot steel challenge matches on a monthly basis and I truly believe these sights have helped my times dramatically!

    Thanks 10-8!

  5. only option 5 Star Review

    Posted by on 18th Jan 2017

    We all know stock glock sights are garbage. I have shot numerous other brands and continue to find something I like better but keep coming up short to these. Hands down, fastest target acquisition I've found.

  6. ALWAYS BEST QUALITY 5 Star Review

    Posted by on 18th Nov 2016

    I'm a repeat customer because 10-8 has provided the best on quality and functionality with their parts. Consistency among like parts is spot on, as is the customer service.

  7. Doesn't Get Any Better 5 Star Review

    Posted by on 20th Oct 2016

    Great sight that fit right on easily with no adjustments. I have this style 10-8 sights on all of the guns I shoot with frequently. They never let me down. The 10-8 performance staff are so nice and professional and always promptly respond to questions.

  8. Great sight, always too short 4 Star Review

    Posted by on 19th Oct 2016

    I love my 10-8 sights. I have them on all of my Glocks. However, I always forget before placing my sihht order. I have to order A taller sight instead of the recommended sight size. I like to have a center hold and always hit high with the recommended sight size. So, to avoid using a 6 O'clock hold I have to order the taller sights, usually one size up.

  9. Great sites and easy to pick up fast. 5 Star Review

    Posted by on 20th May 2016

    As my eyes get a little older the three dot system was getting a little busy while doing training. I like the tritium front and blacked out rear. I will say that 10-8 really makes a solid point if you have a light on your gun. It makes night sites fairly useless. I keep the front just in case I have a flashlight failure. Also after years in LE I have really yet to see a time when there was not some form of lighting where ever you are.

  10. The Best there is 5 Star Review
