The listed sights are our only offerings which are 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.
We recommend our Glock Rear Sight, Low Profile, Standard Height (.250" net blade height) and a .250" tall front. This combination will be effective whether you are running irons only or most brands of adapter plates with an RMSc footprint optic such as the Holosun 407k/507k/EPS/EPS Carry and others. These sights are NOT compatible with the Trijicon RMRcc as it has a very tall deck height.
