About This Firearm
The Glock G23 Gen5 is a compact striker-fired .40 S&W built for duty carry and home defense, holding 13 rounds. Its Safe Action trigger breaks at 5.8 lbs and weighs the same on every shot, and three magazines come in the box.
Gen5 added interchangeable beavertail backstraps and a reversible extended magazine catch. The slide and barrel carry Glock's nDLC finish, and the slide has no optic cut. At 7.28 inches long and 1.34 inches across on a 4.02-inch barrel, the gun is shorter and lower than the full-size G22 Gen5 while keeping the same slide width.
If you're cross-shopping, the Glock G22 Gen5 is the full-size gun at 15 rounds and 28.43 oz on a 4.49-inch barrel, 1.76 oz heavier with nearly half an inch more grip height. The Glock G27 Gen5 goes smaller again, 9 rounds at 23.85 oz on a 3.43-inch barrel with a 4.21-inch grip.

Strengths & Limitations
- The frame is polymer over hardened steel guides, so the rails under the slide are metal.
- The beavertail backstraps fill the space behind the web of the hand.
- The extended magazine catch sits where a thumb reaches it without breaking the firing grip.
- Nothing about the trigger adjusts, so the pull stays at 5.8 lbs.
- Thirteen rounds of .40 is two short of the full-size gun in a pistol 0.67 inch shorter.
- Backstraps are the whole grip adjustment, and the grip angle is fixed.

Frequently Asked Questions
Is there an optic-ready G23 Gen5?
Yes, and it is the version Glock’s US site now lists. The MOS slide is cut for an adapter plate; this non-MOS slide has no cut and cannot be converted.
What else comes in the case?
A magazine speed loader, a cleaning set, the backstrap set and a cable lock.
How many magazines come with it?
Three in the US, one in the pistol and two spares.
Is the slide the same width as the full-size gun?
Yes. They share the slide width, and the length and the grip height differ.
