JT Defense, out of Northern California has recently released a Glock red dot optics mount, to fit into the dovetail of an existing Glock. In addition to being mounted in the dovetail, an extra layer of stability is added by replacing the rear slide locking plate and having this connect to the JT Defense mount. Currently the company lists these optics as compatible with the pre drilled threaded holes on the plate: Burris Fastfire II or III, Vortex Viper, Docter Optic, Primary Arms Reflex. It says “in addition to others” but I would have liked for the company to list these “others”.

Slide mounted red optics break into two camps, the competition and the low vis side. Competitors want their optics to move while firing, and thus usually have overly large mounts, while the low vis side is going for changing as little to the handgun as possible and still having it fit in holsters, be somewhat concealable. This camp then breaks into keeping the rear site or not keeping the rear sight of the handgun. Keeping the rear sight usually means milling out the slide in some fashion, to allow the rear sight to co witness with the front sight through the red dot. However the not keeping the rear sight camp is in this category of JT Defense, with removing the rear sight. I’ve personally seen this on my Glock with a dovetail mounted red dot optic. JT Defense looks to be able to provide a much more solid footing when it comes to that stability by incorporating a second or third point of contact with the slide, by using the slide locking plate.

It is called the Sight Optic Base (S.O.B) and is retailing for $99.95. It comes in two different versions, a narrow and a wide.
