I have several Glock pistols and this one is just as nice. The only thing that I didn’t like about the buying experience is that I was certain that I ordered the model with 13 round magazines and received 10 round mags.

Glock 21 Gen3 First Impression

The Glock 21 is definitely on the larger and heavier side compared to models like the Glock 19, which can feel a bit bulky for those used to smaller handguns. The thicker grip might also be a challenge for shooters with smaller hands. However, we are pleasantly surprised by how well it handles recoil for a .45 ACP, making follow-up shots easier than expected. It’s also pretty accurate, even at different distances, and we find it enjoyable to shoot.

Ergonomics

The grip on the Glock 21 is noticeably larger compared to other Glock models, and for those with smaller hands, it might feel like you’re gripping more than you’re used to. It can be a bit of a stretch, making it tricky to reach the trigger or control the gun as easily comfortably. But, if you can handle the size, that bigger grip offers a really solid hold, which gives you more control during shooting. It feels planted and steady in your hand, especially when you’re dealing with the recoil of a .45 ACP. It’s definitely worth trying out if you can manage the size!

Accessory Compatibility

The Glock 21 Gen 3 comes with an accessory rail, which is a nice touch if you like to customize your firearms. Whether you want to mount a light for better visibility or a laser for quicker target acquisition, this rail makes it super easy to upgrade the gun to fit your needs. It really adds to the versatility, especially if you’re using it for tactical purposes or home defense. Plus, having the option to throw on different accessories just adds another layer of personalization, making the Glock 21 Gen 3 even more adaptable to whatever you’ve got planned for it.

Trigger

The Glock 21 Gen 3’s trigger pull comes in at about 5.5 pounds, which is pretty standard for a Glock. It’s got that familiar, consistent feel that Glock fans appreciate. It’s nothing too light or too heavy, just right for staying in control. You can count on it to be reliable every time you pull the trigger, which is one of the reasons Glocks are so popular. The trigger action is smooth and predictable, so you can stay on target with confidence.
