This review of the new Glock Gen 6 G45, purchased by the reviewer, highlights incremental improvements over the Gen 5, particularly in grip texture and the integrated beaver tail, which significantly reduces slide bite. While the pistol maintains Glock's renowned reliability, the reviewer notes missed opportunities in areas like the optics cut depth and plastic optic plates, suggesting it's a solid evolution rather than a revolutionary leap. The review emphasizes that existing Gen 5 owners with custom modifications may not find a compelling reason to upgrade.

Quick Summary

The new Glock Gen 6 G45 offers notable ergonomic improvements over the Gen 5, including more aggressive grip textures and an integrated beaver tail that effectively prevents slide bite. While it maintains Glock's legendary reliability, the optics cut remains shallow, and the plastic optic plates are a point of criticism compared to competitors.

Frequently Asked Questions

What are the main improvements in the Glock Gen 6 G45 compared to the Gen 5?

The Gen 6 Glock G45 features significantly improved grip textures that are more aggressive and comfortable. It also includes an integrated beaver tail built into the frame, which effectively prevents slide bite for users with a high grip. The slide serrations are also deeper than the Gen 5, offering better manipulation.

How does the optics cut on the Glock Gen 6 G45 perform?

The optics cut on the Gen 6 is an improvement over the older MOS system but is still considered shallow. It prevents co-witnessing with most duty-sized optics and factory sights, and the included plastic optic plates are a point of criticism, with many users preferring metal plates found on competing firearms.

Is the trigger on the Glock Gen 6 G45 a significant upgrade?

The Gen 6 features a flat-faced trigger shoe that feels better in hand than the Gen 5's. While the trigger pull weight is comparable, the Gen 6 has a less defined wall compared to some Gen 5 models and competitors, offering a more consistent rolling brake rather than a crisp break.

Should I upgrade from a Glock Gen 5 to a Gen 6 G45?

If you already own a Gen 5 Glock and have performed custom grip work or trigger modifications, upgrading to a Gen 6 may not be worth the cost, as the improvements are incremental. However, if you are new to Glocks or have a Gen 5 without modifications, the Gen 6 offers notable ergonomic enhancements.
