Have you tried any of the XS Sights? They make several models of sights, some of them available in suppressor height. Back in the day I used to install 3 Dot Trijicon sets on semi-auto pistols, but a few years back I went to XS Sights DXT Standard Dots. Now that the newer version of the DXT (DXT2) is out, XS stopped listing the DXTs' on their web site, but they still sell them. I don't know if the DXTs' are old stock, but I prefer them to the DXT2 (in either Standard Dot or Big Dot), and XS Sights has a "No Questions Asked Warranty" (to the original purchaser) for 12 Years so they'll warranty them if they stop glowing.
Anyway, I like the DXTs' design because the DXT's shallow "V" rear sight doesn't obscure the area around the front sight like notched rear sights do. This very simple sight system is low profile with smooth edges so it works well for CCW. Just "dot the i" and WYSIWYG (
what-you-see-is-what you-get). One caveat is that users who mount a Big Dot Set may have to enlarge the front sight channel on a Kydex holster. Shooters with leather holster may be SOL (unless your holster manufacturer can tailor the front sight channel to accommodate the Big Dot front sight).
Below are some photos of a (XS) DXT Standard DOT Set mounted on a G43X "Rail" (G43X Slide mounted on a G43X/G48 MOS Frame). Glock sells this configuration in Europe as the "G43X Rail".
