Top 4 Features: Glock 23 Vs Glock 21
1. Accuracy and Handling
Glock 23
The Glock 23 is quite a performer in terms of accuracy. During my range sessions, I noticed it handled well with quick target acquisition.
The recoil is manageable, but some shooters might find it snappier compared to larger calibers. It’s a reliable choice for both beginners and experienced shooters.
Glock 21
The Glock 21 shines in this area. Its heavier frame helps absorb recoil better, making it easier to maintain accuracy, especially in rapid-fire scenarios. In my tests, the accuracy was impressive, with tight groupings even at longer distances.
Winner
The Glock 21 takes the trophy in this category. Its superior recoil management and consistent accuracy give it an edge over the Glock 23.
2. Magazine Capacity and Versatility
Glock 23
The Glock 23 comes standard with a 13-round magazine, but you have the option to upgrade to higher capacities. I tested it with various magazine sizes, and even with the larger magazines, it remained relatively easy to handle.
The versatility in magazine options makes it suitable for different scenarios, from daily carry to range shooting.
Glock 21
The Glock 21 also starts with a 13-round magazine, but unlike the Glock 23, it doesn’t offer higher capacity options. This limitation might be a drawback for those looking for more firepower.
During testing, the standard magazine performed well, but I couldn’t help but wish for more capacity options.
Winner
The Glock 23 edges out the Glock 21 here due to its greater flexibility in magazine capacities. This versatility makes it adaptable to more situations.
3. Recoil and Control
Glock 23
The Glock 23, with its .40 S&W caliber, offers a unique recoil experience. In my field tests, I noticed that the recoil is snappier compared to larger calibers, but it’s still very manageable. This crisp recoil response allows for quick follow-up shots.
The compact design of the G23 aids in maintaining control, especially in rapid firing scenarios. It’s a great choice for those who are comfortable with a bit of snap in their shooting.
Glock 21
Now, the Glock 21, chambered in .45 ACP, has a distinctly different recoil. It’s more of a push than a snap. During my testing, this translated to greater control and smoother follow-up shots.
The heavier frame of the G21 helps absorb the recoil efficiently, making it a comfortable option for extended shooting sessions. It’s particularly friendly for shooters who prefer a more steady and controlled shooting experience.
Winner
It’s a close call, but the Glock 21 edges out due to its smoother recoil and greater control. It’s especially favorable for those who spend long hours at the range or in tactical situations.

Glock 21
The Glock 21 matches its sibling in terms of durability. It’s built to last and withstands harsh conditions with ease. My field tests confirmed that it’s as rugged as any Glock.
The larger frame does mean a bit more surface to maintain, but it’s nothing daunting. Regular cleaning and occasional maintenance keep it running smoothly.
