Strike Industries is developing a rear sight rail for Glock pistols so you can add a red dot or other optic to your Austrianhandgun without having to do any machine work on your pistol’s slide.
Right now, Strike Industries has not published a lot of information on the rail, but it would appear to be a short Picatinny rail that mounts to the Glock by use of the normal rear sight dovetail. Â This should mean that a shooter could merely tap out the factory sight and install this rail. Â He or she could then drop the optic of choice onto the rail.
There have been several firearms trainers who have experimented with adding a reflex-type sight to the top of a handgun. Â I think I first saw Dave Spaulding write about this nearly 10 years ago when he was surveying the effectiveness of different sighting systems.
More recently, I have seen Gabe Suarez really push the concept of a reflex sight on your handgun. Â In fact, One Source Tactical, a Suarez company, offers several services where they will modify your pistol’s slide and mount a Trijicon RMR to it. Â They currently offer the service for Glock, Smith & Wesson M&P and SIG Sauer P220/P226 pistols. However, compared to the Strike Industries rail, this is a much more expensive option.
I think that a reflex-style sight on a pistol would enhance accuracy in combat shooting situations. Â They are very easy to use, fast to acquire and reasonably accurate. Â Having a Glock rear sight rail that would allow you to easily add an optic could be a real windfall. Â Two concerns do come to my mind, though.
The first is carry. Â Some holsters and carry styles my not work when you attach an optic on top of your slide. Â While the optics are ruggedized, I doubt any of them are as bulletproof as a plain steel sight. Â The Glock sight rail is likely to bump up the height of the optic a little more than if the optic was attached directly to the slide. Â So, there is a greater chance of banging it off of things.
The second concern I have is the influence the added optics will have with slide velocity and therefore, reliability. Â I know that the Suarez crew has done a lot of shooting and testing of the sights they are mounting to pistols, so I have an expectation that those will run reliably.
Dropping a rail onto the top of the slide and mounting any number of different optics to it will undoubtably have varying affects on how the pistol runs. Â All of the combinations are likely to be heavier, not lighter, than the factory rear sight. Â So, how will the heavier weight, and presumably slower slide velocity, impact the gun’s functioning?
Like with all modifications, I would strongly suggest testing the Glock rear sight rail and chosen optic with a lot of ammo and live fire before relying on it to save your life.
