GLOCK, a name synonymous with durability, reliability, and innovation, has continually set benchmarks in the firearms industry. Among its widely renowned models is the GLOCK 37 (G37) Gen4 .45 GAP Pistol, a firearm designed with power and versatility in mind. This article will delve deep into the G37 Gen4, exploring its unique features, design, and the distinctive .45 GAP (Glock Automatic Pistol) round that sets it apart.

The GLOCK 37 Gen4 is part of GLOCK’s legacy of high-performance handguns, specifically tailored for users who prefer the balance of power and control in their firearm. Chambered in .45 GAP, this pistol combines the stopping power of a .45-caliber round with the compact dimensions typical of GLOCK’s midsize models. It was designed to address the needs of law enforcement, military personnel, and civilian enthusiasts looking for a reliable, easily manageable handgun.

Before diving into the specifics of the G37 Gen4, it’s essential to understand the .45 GAP cartridge. Developed by GLOCK in collaboration with CCI/Speer in 2003, the .45 GAP round was created to offer .45 ACP-like ballistics in a smaller package, ensuring better concealability and handling. It provides the same stopping power as the .45 ACP but in a shorter case, allowing for a more compact grip and overall frame design.

The .45 GAP has become a popular choice for users who seek a pistol that delivers .45-caliber performance without the bulk typically associated with the .45 ACP.

The G37 Gen4 follows GLOCK’s tradition of engineering excellence, with a number of modern updates that make it a popular choice for professionals and civilians alike. Here’s a breakdown of its most important features:

One of the standout features of the G37 Gen4 is its Modular Backstrap System, which allows users to customize the grip size to fit their hand perfectly. This adaptability is a game-changer for shooters of different hand sizes, offering improved control and comfort. The system comes with two backstrap extensions that can be easily installed or removed to modify the grip’s circumference.

The Gen4 model of the G37 also features GLOCK’s advanced dual recoil spring assembly. This design helps to reduce felt recoil and extends the life of the firearm’s internal components. The reduced recoil not only enhances shooting accuracy but also allows for faster follow-up shots, making it an ideal choice for both defensive and tactical applications.

Another enhancement in the G37 Gen4 is its enlarged, reversible magazine catch. This feature allows left- and right-handed shooters to easily release the magazine without having to adjust their grip significantly. The larger surface area of the catch also ensures quicker and smoother magazine changes, an essential feature in high-pressure situations.

Like all GLOCK pistols, the G37 Gen4 comes equipped with GLOCK’s signature Safe Action® System. This system consists of three independent, automatic safeties: the trigger safety, firing pin safety, and drop safety. These features work together to ensure that the pistol only fires when the trigger is deliberately pulled, reducing the risk of accidental discharge.

To truly appreciate the G37 Gen4, it’s important to look at its technical specifications:

•Caliber: .45 GAP

•Length: 7.32 inches

•Height: 5.43 inches

•Width: 1.27 inches

•Barrel Length: 4.49 inches

•Weight (unloaded): 27.68 oz

•Magazine Capacity: 10 rounds

•Trigger Pull: 5.5 lbs.

•Sights: Fixed GLOCK sights

These specs place the G37 in the midsize category, offering a balance between concealability and firepower.

When it comes to performance, the GLOCK 37 Gen4 does not disappoint. The .45 GAP round delivers a powerful punch, offering excellent stopping power, while the Gen4’s enhanced ergonomics ensure that the recoil is manageable. Here are a few aspects of the G37 Gen4’s performance worth noting:

Out of the box, the G37 Gen4 is an accurate firearm, as most GLOCK models are known for their inherent precision. The fixed GLOCK sights allow for quick target acquisition, making it an excellent choice for defensive shooting. With its manageable recoil and crisp trigger break, shooters can confidently place shots on target at various distances.

One of the primary concerns with high-caliber pistols is recoil. The GLOCK 37 Gen4, however, handles recoil exceptionally well due to its dual recoil spring assembly and ergonomic grip design. While the .45 GAP round packs a powerful punch, the recoil is noticeably softer compared to the traditional .45 ACP.

GLOCK handguns are known for their reliability under adverse conditions, and the G37 Gen4 is no exception. It performs well in various environments—whether it’s hot, cold, wet, or dry. The use of high-quality materials and GLOCK’s famous Tenifer coating ensures that this firearm will function reliably for many years with minimal maintenance.

The .45 GAP cartridge plays a significant role in the performance and appeal of the G37 Gen4. Here’s why it’s a preferred choice for many shooters:

The .45 GAP allows for a more compact grip and frame size compared to the .45 ACP while still offering similar ballistics. This smaller frame makes the G37 Gen4 easier to handle, especially for users with smaller hands. The cartridge’s design helps GLOCK achieve the perfect balance between size, power, and comfort.

Many law enforcement agencies have adopted the .45 GAP round and the GLOCK 37 due to its superior stopping power and ease of use. The round’s ballistic performance closely mimics that of the .45 ACP, a trusted caliber in law enforcement, without the added bulk and weight of larger pistols.

Although not as widely available as 9mm or .45 ACP rounds, .45 GAP ammunition is still reasonably accessible. Many gun shops and online retailers stock the round, and while prices may be slightly higher than more common calibers, the benefits of the .45 GAP make it a worthwhile investment for those looking for high performance in a compact firearm.

When comparing the GLOCK 37 Gen4 to other .45-caliber pistols, the .45 GAP’s compactness stands out. Let’s compare it to two popular alternatives: the GLOCK 21 (chambered in .45 ACP) and the Springfield XD-M .45 ACP.

The GLOCK 21, chambered in .45 ACP, is a full-size pistol known for its stopping power. However, it has a larger frame and bulkier dimensions, making it harder to conceal and less comfortable for shooters with smaller hands. The G37 Gen4, on the other hand, offers similar performance in a more compact frame, making it a better choice for everyday carry and concealed use.

The Springfield XD-M is another popular .45-caliber pistol, known for its ergonomic design and customizable features. However, it is bulkier than the G37 Gen4, and its recoil can be more challenging to manage due to its lack of a dual recoil spring system. The GLOCK 37 Gen4 offers superior recoil management, especially with the .45 GAP round, which allows for faster follow-up shots and more comfortable shooting sessions.

Like all GLOCK pistols, the G37 Gen4 is designed to be easy to maintain. Regular cleaning and proper care will ensure that it performs reliably for years to come.

The GLOCK 37 Gen4 features GLOCK’s simple disassembly process, allowing users to easily field-strip the pistol for cleaning. Regular cleaning, especially after firing, will help maintain the firearm’s accuracy and reliability.

It’s essential to apply proper lubrication to the GLOCK 37 Gen4’s moving parts, including the barrel, slide, and trigger components. GLOCK recommends storing the firearm in a cool, dry place and periodically checking it for signs of wear or corrosion.

The GLOCK 37 Gen4 is an excellent choice for those who want the power of a .45-caliber round in a more compact, manageable package. Its combination of the .45 GAP cartridge, advanced recoil management, and customizable grip make it a standout option for both personal defense and professional use.
