The GLOCK G27 GEN 5 might be one of the most underrated handguns on the market. At first glance, the G27 looks like a standard GLOCK pistol, with some intriguing new features that set it apart from the rest of the company’s offerings. The G27 is classified as a subcompact 9mm handgun, and is one of the most popular concealed carry guns on the market. The GEN 5 version of the G27 is the latest iteration of the gun, and it features a lot of upgrades that make it even more appealing for those who are looking for a reliable and concealable handgun. In this review, we will take a look at the G27 GEN 5’s features, performance, and price, and discuss why it is such a great option for anyone looking for a concealed carry gun.

As with all GLOCK handguns, the G27 GEN 5 is made out of polymer, which is strong enough to withstand rough conditions and repeated use. The frame and slide are both black in this case, and the gun has finger grooves and texturing that are designed to provide a comfortable and ergonomic grip. The magazine release, takedown lever, and slide release are all recessed to make this gun easier to conceal, and the magazine capacity is 10 rounds, which is plenty for self-defense purposes.

In terms of performance, the G27 GEN 5 is one of the most reliable handguns on the market. It has a reliable striker-fired action, and the trigger reset is equal to any other GLOCK handgun. The trigger itself is pre-cocked at the factory, which ensures that it does not need to be cocked during reloading. The trigger pull is smooth and predictable, and the gun has a light recoil that makes it comfortable to fire. This gun is also exceptionally accurate, and can easily hit targets at short and long range.

Perhaps one of the most noteworthy features of the G27 GEN 5 is its new Modular Optic System (MOS). This feature allows users to mount an optic of their choice, such as a red dot sight, onto the slide without the need for any special tools or modifications. This makes the G27 GEN 5 one of the most versatile handguns on the market, and allows it to be used for both target shooting and home defense.

The GLOCK G27 GEN 5 is one of the most affordable handguns on the market, with an MSRP of just $499. This makes it a great option for those who are looking for a concealed carry gun, but don’t want to break the bank. Additionally, GLOCK offers a number of accessories that can be purchased separately, such as holsters, spare magazines, and other items, which can be used to customize the gun to an individual’s preference.

In conclusion, the GLOCK G27 GEN 5 is an excellent choice for anyone who is looking for a reliable and concealable handgun. The gun is incredibly easy to use and maintain, and its low price makes it an even more attractive option. The MOS feature allows for a variety of accessories to be mounted onto the gun, while its accuracy and reliability make it a great choice for target shooting and home defense.
