Description
Running a red dot on your Glock MOS is great until you realize your iron sights are either buried in the optic window or don't line up at all. The XS Minimalist OR set solves that headache. These are low-profile backup iron sights built specifically to sit at the right height for optic-ready pistols, so you get a proper co-witness without doing any of the math yourself. Mount them, run your dot, and if the optic ever goes dark you've still got a clean sight picture waiting underneath.
The front sight on this GL-M201P-4 model carries a tritium lamp, so you get a glowing aiming point in low light that runs off the isotope with no batteries involved. Up front you get fast target acquisition day or night, and the rear stays deliberately simple. XS blacks out the rear and cuts serrations across the face to cut down on glare from sunlight and flashlights alike, which pulls your eye straight to the front post where it belongs.
What Makes the Minimalist OR Different
Instead of guessing at suppressor-height numbers, XS standardized one iron sight height that works with their optic plates and keeps the irons low enough to avoid cluttering the window. The sights are CNC machined from solid steel bar stock in Fort Worth, Texas, then given a BlackNitride surface treatment for corrosion resistance and a low-glare finish. That steel construction holds up to racking off barricades and the kind of daily carry abuse that eats up cheaper sights.
Fit and Real-World Use
These fit Glock MOS models including the 17, 19, 34, 45, and 47, and they'll also work on plenty of aftermarket Glock slides. Reviewers who've run them alongside RMR and ACRO footprint optics found the irons and dot lined up nicely, giving a usable backup picture whether you're looking through the glass or straight down the notch. It's a straightforward, no-nonsense setup for anyone who wants their red dot to be the star and their irons to quietly do their job when needed.

Frequently Asked Questions
Do the XS Minimalist OR sights co-witness with my red dot automatically?
Yes, that's the whole point of the OR design. XS standardized one iron sight height so they eliminate the need for suppressor-height calculations and give you a low co-witness right out of the box. Pair them with an XS or Glock MOS optic plate and the irons sit low enough to stay out of your way in the optic window.
Which Glock models do these Minimalist OR sights fit?
They're built for Glock MOS pistols including the 17, 19, 34, 45, and 47. They'll also fit many aftermarket Glock slides cut for standard XS-pattern sights. If you're running an RMR or ACRO footprint optic, these are designed to line up with those plate systems.
Does the front sight glow in the dark?
This GL-M201P-4 model uses a tritium front sight, which glows on its own in low light without batteries or charging. That gives you a bright aiming point day or night. The rear stays blacked out and serrated so all your attention lands on that glowing front post.
Is this the sights-only set or does it include an optic plate?
This SKU is the sights-only set, meaning a tritium front and the blacked-out serrated rear. XS also sells bundles that pair these irons with an RMR or ACRO optic plate and mounting hardware if you want a complete one-box solution. If you already have a plate you like, the standalone sights are the way to go.
