Glock pistols are one of the most popular handguns in the world. Their reliability, durability, and ease of use have made them a favorite among law enforcement, military personnel, and civilians alike. With each new generation, Glock introduces improvements and upgrades to their pistols.

The Differences Between Gen 3 & Gen 4 Glocks

Since both generations are fairly close to one another it can be fairly difficult to find the dissimilarities between them. There happens to be a lot of difference when it comes to Gen 3 compared to Gen 4 and we're going to explain in detail exactly what those are.

Gen 3 Glocks

Gen 3 Glocks were introduced in 1998 and were the standard for Glock pistols until the release of the Gen 4 in 2010. Some of the key features of the Gen 3 Glocks include:

• Dual Recoil Spring: The Gen 3 Glocks feature a dual recoil spring assembly. This improves the longevity of the pistol and reduces felt recoil.
• Finger Grooves: The grip of the Gen 3 Glocks includes finger grooves that are designed to improve grip and control.
• Magazine Release: The magazine release button on the Gen 3 Glocks is located on the left side of the pistol and is not reversible.
• Rough Textured Frame: The frame of the Gen 3 Glocks features a rough texture that provides a secure grip.
• Trigger: The trigger pull weight on the Gen 3 Glocks is approximately 5.5 pounds.

Gen 4 Glocks

The Gen 4 Glocks were introduced in 2010 and include several upgrades and improvements over the Gen 3 models. Some of the key features of the Gen 4 Glocks include:

• Interchangeable Backstraps: The Gen 4 Glocks include interchangeable backstraps that allow the shooter to customize the grip to their hand size.
• Magazine Release: The magazine release button on the Gen 4 Glocks is reversible, allowing left-handed shooters to easily release the magazine.
• Rough Textured Frame: The frame of the Gen 4 Glocks features an updated rough texture that provides a more secure grip than the Gen 3 models.
• Dual Recoil Spring: The Gen 4 Glocks also include a dual recoil spring assembly, like the Gen 3 models.
• Trigger: The trigger pull weight on the Gen 4 Glocks is approximately 5.5 pounds, like the Gen 3 models.
• Modular Optics System: Some models of the Gen 4 Glocks include a modular optics system that allows for the easy installation of red dot sights.

Which Generation of Glock is Right for You?

Both the Gen 3 and Gen 4 Glocks are reliable and durable handguns. The decision of which generation to choose largely depends on personal preference and intended use. Here are some factors to consider when making your decision:

• Grip: If you have smaller or larger hands, you may prefer the Gen 4 Glocks with their interchangeable backstraps.
• Magazine Release: If you are left-handed or prefer to use your right thumb to release the magazine, you may prefer the reversible magazine release on the Gen 4 Glocks.
• Optics: If you plan to use a red dot sight on your pistol, you may want to consider a Gen 4 Glock that includes a modular optics system.
• Price: Gen 3 Glocks are generally less expensive than Generation 4 models, so if price is a factor, you may want to consider a Gen 3 model.

Generally speaking, both generations of Glock include durable and trustworthy models. The Gen 4 models include several upgrades and improvements over the Generation 3 models, such as interchangeable backstraps and a reversible magazine release. However, the decision of which generation to choose largely depends on personal preference and intended use. Consider factors such as grip, magazine release, optics, and price when making your final decision.
