Front Sight: Serrated Green Tritium .125” wide x .225” tall
Rear Sight: Plain Yellow Tritium .235″ tall OR .250” tall x .150” wide notch
GS412 Includes: .015″ G-Shim (front sight shim)
Part Number GS412 (Standard .250” tall tritium rear sight with .225” tall tritium front sight)
All Glock models. Not for MOS.
One G-Shim is included with each set of GS412 Defense Tritium Standard Glock sights.
G-Shim increases the front sight height by .015” and will lower POI by 1”-3” on average, depending on the gun model and target distance. The G-Shim fit is tight on the front sight boss. Use only one G-Shim per front sight.
.225” tall (and the former .215”) front sights may produce a higher POI with most GEN 4, GEN 5 standard models and all Longslides. If POI is high, you can use a hold with more of the target visible above the front sight, also known as a “6-oclock” hold. G-Shim accessory can lower POI 1”-3” on average.
GS412 Defense rear sight will fit Slimline Glock models but will appear slightly large. Outer width of rear sight remains inside of slide width.
Part Number GS731 (Slimline .235” tall tritium rear sight with .225” tall tritium front sight)
Slimline Glock models. Not for MOS.
GS731 Slimline Defense rear sights will fit Standard Glock models but will appear small in relation to slide width.
DEFENSE TRITIUM SIGHT Notes:
Front sight height recommendations are determined by the Point of Aim (POA) and Point of Impact (POI) test results using factory stock Glock pistols with Sevigny Performance rear sights. Test distances are 45-75 feet.
Gun model, barrel type, ammunition, lighting and shooter all contribute to individual POA/POI results.
With drift adjustable only sights, it is recommended the shooter learns correct POA once point once POI elevation results are discovered.

These sights are amazing! I found out Sevigny sights from Warrior Poet Society, and after buying one set, I bought them for all my Glock pistols. The two-dot arrangement is FAR better than the three-dot arrangement of other sites on the market. The narrower front sight is also awesome, allowing you to really center your front sight between the rear without losing laser focus on the front sight.

I love these sights, purchased the slimline for Glock 36 originally but if you are going to get these for Glock 36 get the regular size not slimline. Ended up using the slimline sights on my Glock 43X and it is just perfect. My only complaint about these sights is that they are not serrated on the rear sight (they have that tactical serration for single handed slide manipulation which is awesome btw) and I just wish they were that would make them on par if not better than HEINE sights but TBH these sights work perfectly fine even though they’re not serrated on the rear sight (facing the rear/where tritium is but they are serrated on the front of the rear sight for single hand manipulation like I said already). Anyone looking to get the best selfdefense sights for a Glock 43/43X get the slimline ones and you won’t be disappointed and the accuracy at the range is great better than my target fiber optic rod sights I had on before from 15-50yards! At night the rear sight is easy to identify and differentiate from the front sight and you can get on target quickly and with confidence that you’ll hit what you’re aiming at. Once again I don’t recommend the slimline version for the Glock 36 but your milage may vary although I doubt it. As for the slimline sight for the Glock 48 that I don’t know for sure and am curious if the extra barrel length/sight radius will make the sights not as accurate as they are on my 43x which IMHO are the best sights I’ve used on my 43x period. If the slimline sights don’t quite work on the 48, you can get a front sight from XS sights and they are .215″ so that could be a solution and also is .215 is too tall you can get the Glock night sights from Glock just the front and see if that plus maybe a g-shim if need can be what is needed for the 48. Remember the g-48 is like a g-19 but a little longer barrel/slide so this is why I’m skeptical about the .235Rx.225F slimline sights but you will need the .235 rear sight on the slimline except for the g-36 due to the width of the slide. The g-36 can house the regular size sight no problem one issue some folks may encounter with the g-36 is that the .225 tall front maybe too short mine needed a .245 front and then it was hitting precisely where you’re aiming. Before I was using a 245 I used 215 and 225 fronts with the 250 rear and they all required aiming low VERY LOW. So YMMV and if you want the best Glock 43x sight get this and if you have some front sights you can play with then you can definitely find the right front sight sight is .225 doesn’t work out for you but these sights are excellent . I wish they also sold just the rear sight too that’d be wonderful. And if they can maybe serrate the rear sight then these would be better than Heine which is probably the only sight you can argue is maybe made a little bit better due to being serrated but these are cheaper even when not on sale and if the serration doesn’t matter then these are better than Heine al the way. Keep up the good work and hope to see you guys maybe make sights for the CZ P10 line up if you could make the first P-10M tritium sights on the market that’d be amazing (so far there are STILL no aftermarket sights for the new p-10m a single stack 7+1 small slim p-10 style pistol)
KEEP UP THE GREAT PRODUCTS AND SERVICES! Think about giving a warranty or replacing tritium service and also maybe a sight recoat service if they get scratched/ damaged.
