Co-witness night sight solution for holosun scs on glock - TRYBE Defense High Glow 3-Dot Tritium Night Sights for Glock

If you have a non-MOS Glock (all Gen4 and below + early Gen5s) and you want to mount a Holosun SCS optical sight on the slide, the preferred option is to have the slide milled out. A feature unique to the SCS is its longer length due to the solar cell array in the rear of the sight's platform (vice on the shroud cover). This increased length overlaps the extractor housing in the Glock's slide (for sure on Glock19s and 26s and probably on all non-MOS Glock models). Due to this impingement of the SCS over the extractor housing, any milling must be done so as not to cut into the extractor channel. Because less metal can be milled out, this raises the SCS higher than it would be in an MOS Glock. The touted feature of the SCS is its ability to allow co-witnessing with standard height iron sights. This is apparently true with MOS Glocks, but because of the above-mentioned issue of impingement of the SCS over the non-MOS Glock extractor channel, the milling process cannot cut too deeply. This results in an increase in height of the SCS, which in turn negates use of stock/standard iron sights - they will not co-witness with the SCS, and you must use suppressor-level sights if you want the iron sights to co-witness with the SCS. The problem is suppressor-height sights are TOO high - you can co-witness OK, but they stick up inordinately high (a potential problem for concealed carry use - snagging on clothing, requirement for holster modification, etc.) Enter the TRYBE tritium night sights for Glock: they make a MEDIUM height model (0.33" height/TRB-AP-SP01-3DTS-MD) that can perfectly co-witness with a Holosun SCS without the excessive height of suppressor sights (the TRYBE suppressor-level sights are 0.469" high). I'm normally a "Trijicon guy", but the TRYBE sights appear to be just as well-made and functional as Trijicons (not sure if Trijicon even makes a medium height sight), plus they're $50+ cheaper than Trijicon tritium sights. The TRYBE medium sights mounted with no issue (using a sight-pusher tool) and they co-witness perfectly with the SCS without sticking up like suppressor-level sights. I will be buying another set for another SCS-equipped Glock.
