Hard to Find good co-witness sights for Glock slimline MOS. These fit the bill and work great.

I'd searched around a little for night sights, mainly because I'm on my 4th variation of the 43. I've had the factory Glock night sights... and I've had some other sights from other companies in their "HD" line. I thought I was stuck with suppressor height sights and had almost just made the decision to wait it out. Then, I stumbled across Night Fision. There wasn't a ton I could find market wise (YouTube, forums), but the product was well presented. And the fact they had an optic specific sight was just even better. I went for it and ordered the optic height Glock 43X sights... and man-o-man.. I'm glad I did. Install was a breeze using my off branded sight tool. Having the ability to still have my irons in the lower 1/3 of my optic is fantastic, because I'll never be stranded. I've got limited usage thus far, but I'm impressed and would definitely recommend.

Trijicon was my go-to for the longest time until I was introduced to Night Fision. Night Fision produces the highest quality sights and I will forever stay loyal to them!

These are the brightest sights I have ever seen. The sights look very tough and reliable.

I have tried ameriglo and truglo, these hands down are much better in terms of build quality and brightness. Installing it was easy, only needed minor sanding to get it to fit on my G19 G4 slide.
