Glock 21 magazine Glock Gen 4 Glock 21, 21SF .45 ACP 13-Round Factory Magazine

This is a 13-round factory magazine for Gen 4 Glock 21 and 21SF pistols in .45 ACP

Glock’s .45 ACP battle pistols are known for their huge limit, easy recoil handling, and super reliable execution. Designed to reliably take care of even the most outrageous conditions, Glock plant magazines are the ONLY choice for serious shooters …

These standard size and standard limit size plant magazines give you 13 high strength ACP .45 bullets in a shatterproof polymer magazine with full length support steel inserts, spring steel wire internals and numbered openings for the observer .

Suitable for Glock 21 and 21 SF pistols.

Glock magazines normally accompany solid springs from the processing plant, but wear out quickly and become easier to stack and unload after a couple of shooting sessions. Consider redesigning the magazine magazine for a significantly longer activation time. Glock loaders are accompanied by an extremely impressive spring rate from the plant to ensure uncompromising quality in the toughest conditions. In some cases, magazines are considered quite difficult to stack right away. In any case, after a couple of times of stacking and unloading, the springs break well and it becomes much easier to stack.

We prescribe the use of a magazine loader to facilitate the stacking system.

For added strength and sturdiness, the implant’s Glock magazines are made of steel internally secured with an unbreakable polymer barrel. This increased robustness gives devoted officials, military and residents the confidence that there will be no problems under heavy preparation.

Glock 21 45

The 45 Auto, also called the 45 ACP, is a bulky cartridge created in 1905 by John Moses Browning. Glock has another take on that cartridge, blending a moderately current design with the 115-year-old round. Does Glock have a practical stage for the car 45, or are the old ways really better? We should look into my Glock 21 study.

A pistol’s accuracy is often its most notable selling point, and the Glock 21 is totally honest. Shots generally were tight and landed where I was aiming with virtually no deflections. Glock is known for his special but strong forms. They are solid and will perform similar to how advertised (we don’t have to argue with the .22 Glock). This quality of form is evident when precision is sought.

I usually shoot my gun between 7 and about 30 yards. Seven to about 15 yards is where I can put my shots on top of each other, plus is where I can rock things in town, but not as unambiguously as I’d like.

At my ideal distance, the groups floated at a variety of ½ inch and 1 inch differences in a standing, unstabilized shooting position. Shots 1 inch away were often the shooter’s mistakes. When I leaned on something, my groups contracted down to ¾ of an inch. I guess he makes himself without any problems.

The GLOCK G21 Gen4 .45 ACP has a 13 + 1 limit and elements an octogonal rifled barrel. The dark tradable backstrap grasp offers a safe hold.

Glock 21 Gen 4 Review .45 ACP Pistol | Gun Review


Glock 21 Gen4 Review, G21 Review, lead
Glock 21 Gen4 Review, G21 Review, lead

The .45 ACP round met with a resurgence in prevalence. In truth, that’s as much as stepping back from the .40 type, as the 9mm is also claiming areas of strength for a. Updates in bullet development have made all weapon modifications more viable, which means that the different variables are more basic: firing position, uncompromising quality, and really putting the best bullet on the road. For those interested in the edge, the 9mm is fast becoming the better choice, but for those hoping to scale up to a bigger shot, the .45 ACP is the best.

With this move comes the requirement for a solid battle weapon. For the vast majority, this means a regular weapon with a supercharged magazine. A large number of these guns, especially in the 1911 phase, are expensive and generally unsuitable for useful transport. The sturdiest of these will generally be the most expensive, setting them away from some shooters. The most ideal decision is many times a polymer based pistol, and this is where the Glock 21 definitely comes in. Having dragged my most memorable Glock 21 on the streets some time ago, I know this pistol well and that equivalent pistol travels in the holster. of an officer to date. However, some doors were opened to him to exchange it for a new firearm, he scolded them all with extraordinary intensity. How come? Since it works, and that official realizes his life depends on him doing just that.

The G21 Gen4’s oversized triggerguard allows for use in any condition—even when you have to wear gloves.

Glock 21 Gen4 Legacy and future

For some, the Glock 21 is the quintessential high-limit .45 type. It has proven to be reliable, accurate and indestructible. With a limit of 13 + 1, it provides effective opening capacity in a proven type. It retains the basic ergonomics and common sense of all Glock pistols and the extras, holsters and extra magazines are plentiful. For those taking the action of the G22, the change is straightforward and simple. Available with overnight plant locations, the G22 prepares out of the container by obligation, flow rate or elsewhere. And all of this is about a fraction of the cost of some high-limit .45s.

“The real contrast here is in the rear straps. Unlike many frames that expect you to wear a flat, the G21 Gen4 starts without straps …”

The main problem with the G21 was its size. It is a larger piece and those with small hands often find it difficult to control it. The short-frame version helped, but the featured progressions on the Glock 21 Gen4 really made the G21 open to more shooters, making other improvements. When dealing with another Glock 21 Gen4 pistol, I initially saw the full grip finish. It’s a decent change from the worse performance of the past and fits well in the hand. It just looks less scratchy while still staying strong.

The next step was the magazine change, which is not only actually reversible, but also much more natural. I found it easier to access without waiting to move the gun into my hold. The button also stays flush with the socket, eliminating many unplanned delivery problems presented by many parts of retailers. It is relatively almost as wonderful as it gets for this stage. The finger grooves on the front strap are beautifully shaped with a matching checkerboard. The edge is cut high on the trigger, considering a strong grip.

Other features of Glock 21 Gen4

The real contrast here is in the back straps. Unlike many systems that use a card, the G21 Gen4 starts with no strings attached. In my “keep it simple” world, this is amazing. Leaving the handle as is provides the shortest activation found in this case dimension to date, with nothing free. Assuming you’re leaning towards the Gen3 feeling, you can essentially add the medium tie. (A thicker tie is accessible for those with much larger hands.) Without a grip board attached, this gun fit me quite well, so I finished all testing on this setup.

To balance the Gen4 package, Glock added a double reaction spring. Generally this will control how the force feels in the hand and can add critical life to the springs. The views provided were the basic shapes, a plain front with white accents, and a recessed U-shaped back illustrated in white. A track is formed on the envelope to recognize strategic lights. Three magazines were delivered along with the same reload tool, as well as the two rear straps and a device intended to remove the retaining pin. Finally, completing the slide is a less polished and complicated piece. It’s more of a dull darkness, which fits the simple reason of the weapon.

Performance of the Glock 21 Gen4

All the G21 pistols I have shot over the years are extremely accurate. Shy of the G20, the G21 cannon is the most reliable standard Glock prepared for me. Testing this weapon turned out to be a special case. The G21s are absolutely accurate and probably the easiest supercharged .45 to fire well. The more limited trigger comes to improve this for me. I got the best accuracy with the Winchester Ranger’s 230-grain SXT settings, with a 1.7-step pickup with a group of four hits within about an inch. The G21 put everything in around 2 crawls at 25 yards. Having had double-cost weapons, they show equivalent or lower accuracy, that’s pretty awesome.

For me, however, the most observable progression in this era is the purchase of magazines. It may not be the most specialized, but it is the most used in preparation. Where this weapon really shines is progress and under pressure. This weapon worked indefinitely without any problems. It’s still one of the smoothest .45 pistols around, making it much easier to keep up with advances in accuracy. The more limited range saw simpler trigger control and the final finish locks this gun really well in my grip. Unloaded with and without gloves, losing your grip on the weapon was unimaginable. It wasn’t hard to get a decent and strong grip on the holster. I tested the G21 Gen4 from both a strategic thigh rig and a similar holster in an OWB-type carrying mode.

The draw was smooth and the sights were quickly raised. For those who need tritium, the weapon can be ordered from the plant with night sights.

For me, however, the most obvious advance of this era is the purchase of magazines. It may not be the most specialized, but it is the most used in preparation. Previously, magazine swaps required a hinged movement of the weapon in my grip to achieve a strong arrival of magazines. The Gen4 get makes it superfluous. In truth, my hands are quite large, however, the catch can be effortlessly reached without a turn, working with extremely fast magazine changes. It does this without adding any joint effort, making unexpected magazine discharges unlikely. All the magazines have actually been released, blank or not. Stacking on the edge was a big part of the last round, but the timing and redundancy are likely to relax the magazines a bit.

The Gen4 grip design provides comfortable texturing for added control, and backstraps of different sizes can be swapped out to provide a better fit.

Dynamics of the weapons site

While attending Glock’s 25th anniversary class at the Gunsite, I was given the option to spend a day with a G21 Gen4 using a medium locking plate. Unlike turning someone else’s gun, I fired with no guarantees. It was immaculate and extremely accurate, during one of the most focused days in the Gunsite 250 class. I was looking forward to the opportunity to configure this gun for my needs and really tackle a lot of hardships. Of all the levels of Glock, this is the one I use most often in my profession as a police officer. The G21 has always been my number 1. In fact, even without the shortened brim, it fits better in my hand than any other pistol.

“Since I’ve never liked ‘better than ever’, my point of view is different because of the G21 …”

It was smarter to shoot the Gen4 variant. The more limited profile improved my ability to shoot well with this gun. The new final finish is perfect, giving a decent blend of punch without the equivalent scrub stain. The standard trigger was not surprising and controllable. The new discharge magazine is ideal for this firearm. Approaching without the need for a joint weapon change in your grip is colossal. It makes quick and positive magazine changes conceivable without neglecting to focus on the danger. This was especially noticeable when shooting on the go. You can simply move, shoot, reload and continue as needed, keeping an eye on danger.

Since I’ve never liked it “better than ever”, my point of view is different because of the G21. Everything that has changed only improves the capabilities of this excellent weapon. If you are looking for a strong and reliable super charge pistol in .45 ACP, be sure to check out this pistol, it will surely dazzle! For more information, visit
