We think the biggest improvement from “Gen 3” is when the gun is used without any of the supplied grip panels in place.

The Generation 4 pistols utilize flat-topped spikes for improved grip. With the largest backstrap in place, we installed the extra-length pin (right arrow, supplied). Note the mag release is almost flush with the grip. We had to turn the gun and press inward at its front corner to release the magazine.
We thought Glock did a particularly good job of providing a clean, recessed crown on our G23 Generation 4 pistol. Glock uses hexagonal rifling in the G23 barrels.
The loaded-chamber indicator consisted of a ridge at the edge of the extractor that could be felt by the index finger in the off trigger position. Easier to feel than it was to see, we found it effective. Admittedly, this only served right-handed shooters.
Glock night sights provided better definition than the standard sights, in our opinion, as well as excellent illumination.
