Are Glock Gen 3 and Gen 4 Slides Compatible?

With a simple yet effective design, and a commitment to quality, Glock has become one of the most widely recognized names in the firearms industry.

Their handguns are known for their reliability and accuracy, making them a top choice for those who demand the best in their equipment.

In this article, the firearms experts at 3CR Tactical focus on a specific aspect of Glock handguns: the interoperability of their slides. Specifically, we answer the question: can you change slides on a Glock?

Are Glock Gen 3 Slides Compatible with Gen 4 Frames?

No, Gen 3 slides aren’t compatible with Gen 4 Glock frames. The primary reason for this is the difference in recoil spring design between the two generations.

The recoil spring in Gen 4 slides is a dual-spring system, while Gen 3 slides use a single-spring system. Additionally, Gen 4 slides have a larger hole in the front of the slide to accommodate the dual-spring system.

However, aftermarket manufacturers have produced slides that are compatible with both Gen 3 and Gen 4 frames, like this Brownells RMR Cut Black Nitride Slide. These slides are designed with a dual-spring system, similar to the Gen 4, but with a smaller hole that fits Gen 3 frames.

What is the Difference Between Gen 3 and Gen 4 Glock Slides?

The differences between Gen 3 and Gen 4 Glock slides are relatively subtle but significant. The most notable difference is the dual-spring recoil system used in Gen 4 slides.

This system provides better recoil management, reduced felt recoil, and faster follow-up shots. The other significant difference is the enlarged magazine release button on Gen 4 slides, which is reversible for left-handed shooters.

Another difference between Gen 3 and Gen 4 slides is the grip texture. Gen 4 slides have a more aggressive texture than Gen 3 slides, providing a more secure grip in adverse conditions. This is especially beneficial for competitive shooters and hunters who may encounter wet or muddy conditions.

Assembled Glock Slides

Assembled Glock slides are a popular option for gun owners who want to upgrade their firearms without the hassle of assembling the parts themselves. These slides come pre-assembled with all the necessary components, including the barrel, sights, and slide completion kit.

Assembled slides are available for both Gen 3 and Gen 4 Glock frames, allowing users to choose the best option for their needs. One of the benefits of assembled Glock slides is that they are ready to install right out of the box.

This saves gun owners time and eliminates the need to purchase additional parts separately. Additionally, assembled slides are available in a variety of colors and finishes, allowing users to customize the appearance of their firearm.

Glock Slide Kits

Glock slide kits are another popular option for gun owners who want to upgrade their firearm. These kits include all the necessary components to build a custom slide, including the slide, barrel, sights, and slide completion kit.

Glock slide kits are available for both Gen 3 and Gen 4 frames, providing users with a wide range of options. The primary benefit of Glock slide kits is that they allow gun owners to customize their firearm to their specific needs.

Users can choose the components they want, including the barrel length, sight type, and finish. Additionally, building a slide from a kit is a fun and rewarding experience for gun enthusiasts.
