Glock 43/43X/48
Sights compatible with the Glock 43, 43X, 43X MOS, 48, 48 MOS.
The Glock 43/43X share the same slide, and the 48 is the same width and geometry but longer.
Since the Glock 43X and 48 are somewhat larger overall due to the frame/grip length, they can accept some full size pistol sights without the sights seeming "too big" on top. We strongly recommend our Glock Rear Sight, Low Profile, Standard Height (.250" net blade height) and a .250" tall front.
Due to the wide variety of possible optic mounting solutions for the Glock 43x/48 MOS, we haven't been able to get data on all of the combinations. Here's what we can tell you so far:
Holosun 407k/507k with C&H Precision adapter plate:
-Glock Rear Sight, Low Profile, Standard Height (.250" above slide) and .250" tall front - provides lower 1/3 cowitness
-Rear of optic is .180" above slide.
**Results above are similar enough with other logical combinations of adapter plate or direct milling.
Trijicon RMRcc with C&H Precision adapter plate:
-Rear of optic sits .350" above slide, too tall for our any of our sight sets
Your amount of cowitness height in the optic window will vary based on your optic and its mount. Use the below measurements to determine if your optic will work. You'll want the rear sight to be at least .060" taller than the rear of the optic (ie. your optic can't sit taller than .190" above the slide, doesn't matter if it's a direct mill or adapter plate).
-Glock Rear Sight, Standard Height, Low Profile = .250" above slide
-Glock Tall MOS Rear Sight = .320" above slide, but is NOT recommended for use with 43x/48
