Features
Gen 4 updates include the dual recoil spring assembly, which softens felt recoil compared to Gen 3 and speeds up split times on follow-up shots. The modular backstrap system lets shooters swap between three grip sizes to fit different hand dimensions. A medium backstrap is installed by default, small and large are included. The rough-texture frame (RTF) grip provides solid purchase without gloves. The Safe Action trigger has its built-in trigger safety and no external manual safeties or decocking levers.
Three magazines included is a real practical benefit. It cuts down on range reloading time and means you're not immediately spending more on spare mags.
Who It's For
The G23 has a long history in law enforcement as a duty sidearm, and that background shows in how the pistol is set up. It suits home defense users, range shooters, and those who carry in a duty context. Sport shooters running USPSA or similar divisions will find 13+1 in .40 is competitive. The used condition means this particular example has been carried or shot before, worth inspecting for wear on the finish and internals before purchase.
Use Cases
Home defense, range training, duty carry, and competitive shooting all fit this pistol. The compact frame balances concealability with the capacity and caliber that many shooters want from a serious defensive handgun.
