Glock 20 Gen 4 Problems: What You Need to Know

For many years, the Glock 20 Gen 4 pistol has been a popular choice for self-defense and concealed carry, though there have been some complaints about its performance. 

In this blog post, we will look at some of the problems with the Glock 20 Gen 4 pistol and see if it is a good choice for those applications. We will also discuss some modifications that can be made to improve its performance and reliability. Lastly, we will compare it to other firearms on the market and see which ones are better suited for those purposes.

Glock 20 Gen 4 Problems to Look into Before Buying a Pistol

The Glock 20 Gen has been a popular choice for several years, but you should be aware of some inherent problems with the design before purchasing one.

  1. It does not cycle reliably with certain types of ammunition, and users have had trouble using Buffalo Bore and Underwood ammo.
  2. The pistol tends to “bite” shooters when firing, which can cause discomfort and lead to poor accuracy. Many have also complained that the grip angle is too steep, making it difficult to hold and shoot accurately.
  3. This pistol is quite large and heavy, which may not be ideal for those looking for a concealed carry weapon.
  4. Although the Glock 20 Gen comes with a standard magazine capacity of 15 rounds, some users have reported that it does not always lock back at the end of their last shot due to an issue with the magazine follower being too small for the spring inside.
  5. The slide can be difficult to manipulate when using gloved hands or under stress due to its lack of serrations and aggressive texturing on top.

Is The Glock 20 Gen 4 Pistol A Good Choice for Self-Defence or Concealed Carry Purposes?

In general, we would say no. There are other firearms on the market better suited for those purposes. If you are set on purchasing a Glock pistol, we would recommend looking at the Glock 17 or 19 instead.

Those models have been revised and improved over the years and have had many problems with the original design fixed. Of course, there is no perfect firearm, and each one has its own unique set of pros and cons, so make sure to do your research before making a final decision.

What Modifications Can Be Made to Improve the Performance of The Glock 20 Gen 4 Pistol?

If you are still interested in purchasing a Glock 20 Gen, some modifications can be made to improve its performance.

  1. One is to install an aftermarket barrel from companies like Buffalo Bore or Underwood Ammo. These barrels are typically machined out of 416R stainless steel and have been precision-fitted to the Glock 20 Gen. They offer improved accuracy and reliability over the stock barrel.
  2. Another option is to replace the factory grips with aftermarket grips with a better grip angle. This will help reduce muzzle flip and make it easier to hold and shoot accurately.
  3. There are also many different types of magazine extensions available for the Glock 20 Gen that will increase its capacity by anywhere from one to six rounds.
  4. Different types of sights on the market can be installed to improve visibility and accuracy.

How Reliable Is the Glock 20 Gen Compared to Other Pistols on The Market Today?

  1. The Glock 20 Gen has a reputation for being very reliable in firing every time you pull the trigger without any malfunctions or stoppages. Yet, it does have some drawbacks regarding reliability, such as its large size and weight making it harder to conceal carry than smaller models.
  2. This pistol does not have any external safety features, which means that it can fire accidentally if dropped or snagged on something.
  3. The magazine release is located right next to the trigger guard, so be careful when handling this gun around other people because they could easily pull out your magazine and cause an unintentional discharge. 

While Glock 20 gens are very reliable overall due to their durable construction and simple design, there have been reports of some models having issues with feeding hollow point ammunition (which may lead them to jam up). This problem can be resolved by replacing your current barrel with one designed for use with these types of rounds.

Are There Any Other Firearms Better Suited for Self-Defense or Concealed Carry Than the Glock 20 Gen?

If you’re looking for a reliable and well-made handgun, we recommend considering either the Smith & Wesson M&P Shield or Ruger LC380. These guns have been designed with concealability in mind while still offering excellent stopping power. 

They also come standard with external safeties that make them safer to handle around children and others who may not know how firearms operate. The only downside is that they both lack an internal hammer (so no second-strike capability if your first shot fails to ignite primer).

The Sig Sauer P320 Compact is another excellent option because it has the same features as its full-sized counterpart. The only difference is that it’s smaller and easier to conceal carry at all times without any discomfort or hassle due to reduced weight of roughly 60% when compared with other compact models such as Glock 19 Gen III/IV, Ruger LC380, Smith & Wesson M&P Shield EZ, etc.).

You can choose between three different calibers: .40 S&W (standard), .357 SIG (optional), or even more impressive firepower than both of those previous rounds combined if you opt for their newest caliber.

It has a polymer frame that is strong enough to withstand up to 400 lbs. of pressure without breaking, making it an ideal choice for someone who wants a gun that will last long and perform reliably under any kind of stress. 

Sig Sauer P320s also come with a modular design that allows the user to change out various components (grips, barrel length, etc.) to suit their individual needs or preferences better.

The Glock 19 Gen III/IV is another excellent choice if you’re looking for something with a bit more stopping power than other models on this list. It also has a slightly longer barrel than models like the Smith & Wesson M&P Shield or Ruger LC380, giving you better range accuracy. 

Note that it is a bit more difficult to conceal carry because of its larger size. It’s chambered in an extremely common round that many police officers carry as their duty sidearm, so finding ammo shouldn’t be too difficult either.

How to Prevent or Minimize Glock 20 Gen 4 Problems from Happening?

One way to help reduce the chances of experiencing any malfunctions with your Glock 20 Gen is to maintain it well. This means regularly cleaning and lubricating all of the moving parts, as well as making sure that there’s no dirt or debris build-up in the barrel. You should also test fire a couple of rounds through your pistol after you’ve performed any maintenance work (even if you only changed the oil), just to make sure that everything is still functioning correctly.

If you experience a jamming issue, try switching out your current barrel for one explicitly designed for use with hollow-point ammunition – this will ensure smooth feeding and prevent any potential stoppages from happening. 

Always remember to keep your gun unloaded when not in use and store it in a safe place where unauthorized individuals cannot access it.

Should I Buy a Glock 20 Gen 4?

The Glock 20 Gen IV is an excellent choice for self-defense or concealed carry, but it’s not the only option out there. If you’re looking for something slightly different that offers more stopping power than the standard .40 S&W round, we recommend considering the Sig Sauer P320 Compact in either .357 SIG or .45 ACP. Both of these calibers offer more knockdown power than the average handgun cartridge. 

If you’re primarily interested in target shooting or home defense, you should opt for a Ruger’s revolver such as the LCRx (which comes chambered in both .38 Special and .357 Magnum). It has a simple design that makes it easy for anyone to operate, and it comes with adjustable sights so you can accurately aim your shots where they need to go. 

Conclusion

The Glock 20 Gen IV is an excellent choice for anyone looking for a reliable, durable, and powerful handgun that can handle just about any situation. With proper maintenance and customization, you can leave behind all your Glock 20 gen 4 problems. 

Remember to keep your gun well-maintained and test fire a few rounds through it after you’ve made any modifications, and you should be good to go!
