Glock Glock 21


The Glock 21 is a semi-automatic large-frame pistol chambered in .45 ACP. Glocks have a simple, dependable and easy-to-use design, which they’re the preferred handgun for many law enforcement agencies.

The G21 has standard Glock features such as a polymer grip that’s lightweight making it 2.4 pounds loaded. On the front of the grip are finger grooves and the sides have a rough texture that feels a bit like sandpaper. Its double-action trigger is also “safe-action” meaning the safety is on the trigger rather than the side. The only way a round can fire is if the shooter pulls the trigger because its internal design won’t allow the firing pin to punch forward any other way. This prevents accidental discharges if the pistol is dropped.

Glock recommends the Glock 21 for open carry.

Editor Review

Way back in 1994, when I made my first leap into law enforcement, I had the opportunity to select which firearm I was to carry to protect myself and the lives of those I served.  I spoke to numerous “old timers” who proclaimed the value of the Dirty Harry type of .44 magnum revolvers and others who saluted the very reliable 9mm semi-autos from a variety of manufacturers.  A gentleman of infinite military repute and experience gave me sage advice.  His words were simple, “Get yourself a .45 and keep it by your side everywhere you go.” 

He further went on to explain to me that should I have to use it there are three things I can rely on:  first, if you’re in tight space, over penetration won’t be as much of an issue to people in other rooms.  It is a slow, fat bullet with a lot of muscle.  Second, because it is a fat bullet, almost 0.5” in diameter, it will deliver awesome impact energy, and third it’s a seriously intimidating piece of weaponry.  The cave like muzzle opening will certainly command and hold a bad guy’s attention.

With this in mind, I selected the Glock 21 in .45ACP.  It was a huge, clunky, black, industrial looking hunk of “plastic” and it drew more than a few scoffs from my partner and colleagues.  Little did we know at the time, that the Glock would soon become the industry standard for law enforcement.

I am no small man and I have large hands.  The size of the Glock 21 was not daunting and if anything it fit my hand quite well.  Its 13-round, double-stacked, high capacity magazine made for a thick grip which suited me just fine.  Because of the perceived power of the .45, I was concerned about recoil, but again, the size of it was an asset.  Recoil was negligible and allowed for fast recovery for successive shots.

Highly accurate and highly destructive in its ability, the Glock 21 proved to be a great sidearm for my purposes.  I did purchase one of the integrated laser sights, which added to its effectiveness.  Since that day, I have purchased a number of other Glocks, including a newer Glock 21, but have yet to take it out of its case.  I still carry that same Glock .45 that I bought 16 years ago.

It is very reliable, never had a malfunction and has successfully chambered and fired thousands of rounds on the range.  It is the handgun that I will pass on to my son when he comes of age.

Bragging on the Glock 21, like I have, I still have to give it only four stars.  That elusive fifth star is held up by its magazine and size.  The size of the gun is appropriate for my hand, but it is certainly difficult to conceal as an off-duty or strictly concealed carry gun.  Glock has begun manufacturing a .45 with a single-stack magazine but it is a subcompact slimline Glock 36.  While still a very desirable handgun and caliber, it is a subcompact firearm in a cannon-like caliber.  I would like to be able to carry a full size Glock .45 with the same slim silhouette that has made the 1911 .45ACP pistol versions so popular.

The .45 is used in numerous special operations units within the law enforcement community and in the military. Numerous departments allow their officers to carry this handgun, but unfortunately for those of us who prefer the .45, the standard for law enforcement is the Glock 22 .40 caliber.  While a fabulous firearm in its own right, it is not a .45.  Police Officers and people in combat-type situations need to be able to share ammunition and magazines if the need arises and the Glock 22 has fit that bill nicely. 

I encourage you to explore the purchase and use of the .45 ACP caliber, especially in the Glock 21.  It is a safe, high functioning, reliable, and well designed handgun.
