How does the Glock Gen 5 slide and finish compare to previous generations?

The Gen 5 slide features a 'bullnose' rounded front for easier holstering and boasts a new nDLC (Nitrate Diamond-Like Carbon) finish, described as a deep black and superior in durability and corrosion resistance compared to the finishes on Gen 4 and earlier models.

What internal changes were made to the Glock Gen 5 frame?

The Gen 5 frame removes the leaf spring for the takedown lever, replacing it with a coil spring similar to the Glock 43. It also features altered frame rail and locking block geometry, a redesigned ejector, and a two-pin system for 9mm variants.

Is the Glock Gen 5 barrel compatible with Gen 4 frames?

No, Gen 4 barrels are not compatible with Gen 5 frames due to significant changes in the barrel locking lug geometry. The Gen 5 guide rod is also longer to accommodate these new dimensions.
