I still remember when the Glock 20 and 21 first came out, and I owned both, That was when I worked for the late Col. Rex Applegate. The Glock 20 is a 10mm pistol, and the Model 21 is chambered in .45 ACP. Other than the chamberings, both guns are alike in many ways. However, the 10mm version didn’t balance as nicely in my hand as the .45 ACP version did. Of course, the 10mm barrel is a little bit thicker, while the .45 ACP version has a barrel that is thinner because of the larger diameter bullet. You’d assume that both guns would feel the same – but they don’t. And, I ran a test with a number of shooters, and they all said the same thing, the Model 21 felt better and balanced better in their hand. So, it wasn’t just me.
For quite a few years, the 10mm round was “the” caliber to have, it would stop a charging rhino with a single shot, or shoot down a jet fighter from 10-miles up. Well, that wasn’t true and it still isn’t! The 10mm was a hard-hitting, and hard recoiling round in any handgun, but with practice, it is controllable. The FBI even went to the Smith & Wesson 1076 chambered in 10mm. The only problem was, like many in law enforcement, they aren’t really into guns, per se. The FBI and most polices departments just weren’t willing to invest the training time and money to properly transition their agents and officers. So, in short order, the FBI abandoned the 10mm and went to the .40 S&W – which is a shorter, and more watered-down round than the 10mm was – but it is still a 10mm diamerter bullet. And many ammo makers started reducing the power of the 10mm, until it was down to near the same power as the .40 S&W.
Today, the 10mm is making a comeback and many ammo makers are once again loading the 10mm caliber to what it used to be. Two ammo makers, Buffalo Bore Ammunition and Double Tap, are making some really hot 10mm rounds these days, and I’ve shot both brands in various 10mm handguns. Of course, we are in the worst ammo drought in history, and all calibers are extremely difficult to find on dealer’s shelves. The 10mm is very difficult to find these days. (It takes either a lot of luck or tools like ammoseek.com, to find any.) Our local small box stores have had no 9mm ammo or .45 ACP on their shelves for several months now, and if you are lucky enough to find some ammo, you are limited to only two boxes per caliber, per day.
The Glock 21 that I have is a Gen 4 version that comes with variety of thickness backstraps. It was made in good ol’ Georgia, USA. Prior to this, the first Generation examples were made in Austria, where Glock is headquartered. Here in the United States, Glock has established a service center as well as actually producing many of their models in Georgia.
A little bit of specification info on the Glock 21 is in order, of course: This is a full-sized service handgun. However, with the right clothing and holster, you can still conceal it fairly well. The Model 21 has a 4.61-inch barrel, making it shorter than a full-sized 1911 Government Model. The gun weighs in at 26.28 ounces, with no magazine in place, and 29.28 ounces with an empty magazine, and roughly 39-ounces with a loaded magazine, depending on bullet weight. The slide is 1.12-inches wide at the widest point, so it is right in there, with a 1911 handgun, and at the widest point, the gun is 1.34-inches wide.Continue reading“Glock 21 .45 ACP Pistol, by Pat Cascio”
