When people say they want a .45 ACP pistol, most people automatically think of the 1911 pistol, but did you know there are other options with higher ammunition capacity?
The Glock 21 was the first of its kind to offer 13+1 rounds of .45 ACP. It’s also one of the most affordable .45 Auto handgun on the market.
Are you looking for a .45 caliber handgun that provides all of the power you’d expect from a .45 but without compromising high quality? If you’re a fan of Glock and the .45 caliber then this could be a good firearm for you.
The Austrian-made Glock 21 pistol with a polymer frame is simply a scaled up version of the original Glock 17.
It’s that Glock shape that everyone either loves or hate. If you’re use to the size on the Glock 17, then the G21 is just slightly larger.
The Glock 21 weighs more than other full-sized Glocks but is still lightweight for a .45 handgun. Let’s take a closer look at what the G21 offers.
Glock 21 Basics
The Glock 21 is the perfect answer to the gun owners who are interested in owning a .45 ACP firearm but love the Glock’s high capacity magazines.
It delivers the power of the .45 ACP round with the standard-issued 13 round capacity magazine. The Glock 21 is a full size firearm with a polymer frame.
The polymer frame means even with its full size, the G21 fully loaded weighs nearly half a pound less than the steel 1911.
The dimensions of the G21 make it a duty-sized pistol. It’s a double stack magazine that is wider than the 1911, but it’s not uncomfortable to hold.
Since the G21 has a higher round capacity, you’ll be thankful that you have an extra round or two if you’re in a situation where you need it.
The slide is made of gas nitrate treated steel and the barrel contains octagonal rifling. A component that is common across Glock models is the striker-fired feature which removes the need for a hammer.
The sights are the standard three-dot sights. The sights are well built, precise, practical, and ready-to-go right out of the box. The sights, overall, can come down to personal preference.
The lower recoil is a significant advantage. Since the Glock 21 has lower recoil, this means more training with less fatigue.
The reduced recoil also offers the ability to accurately fire follow up shots more quickly. Many people regard the G21 as one of the smoothest-firing .45 caliber pistols they’ve ever held.
The one thing I like about Glock is the ability to customize. Glock offers more options for accessory and customization than any other handgun company.
There’s so many options for gun owners to tweak or swap out, making their gun their own. The polymer frame features a Picatinny compatible rail and accepts any number of accessories from sights, grips, holsters, lasers, and lights. You could spend hours upon hours adjusting and perfecting your Glock 21.

- Trigger Pull / In Use
The trigger pull is like any Glock trigger, fitted with a 5.5 lb. pull which is standard. Glock triggers can be heavy and difficult to manipulate but with practice, you’ll get a better feel on it.
The trigger pull can initially throw off your accuracy, but it doesn’t take long to become accustomed to it. Reduced trigger weight connectors are available if you want a lighter pull.
Glock pistols also feature three safeties that disengage once the trigger is pressed: the trigger safety, the firing safety, and the drop safety.
The trigger safety which is incorporated into the trigger and when engaged, blocks the trigger from moving backwards.
The trigger and the trigger safety must be engaged together in order to fire. The firing pin safety is a spring loaded blocker of the firing pin. And finally, the drop safety is a trigger bar prevents unwanted firing from occurring in the event the pistol is dropped. If you like the Glock triggers then you won’t have any problems with the Glock 21.
What is the biggest advantage of having a .45 ACP pistol aside from the power? Answer: the ammunition variety. There’s so much ammo out there because of the .45’s popularity. Even so, the .45 Automatic Colt Pistol (ACP) round is fairly controversial. Invented in 1905 by firearms designer John Moses Browning, the .45 was the standard caliber of the Colt M1911 Pistol and remains so to this day.
This heavy subsonic bullet weighs twice as much as the 9mm round and delivers a third more energy. Today, advances in bullet technology means a 9mm round can deliver as much energy as the .45 ACP. Despite this, the .45 ACP is far from dead, as it has also benefited from advances in ballistic technology. There are more choices of .45 ACP pistols than ever before, as almost all ammunition manufacturers offer several lines in the big caliber.
