This video from SHOT Show 2011 features Mike McAvoy, a Glock District Manager, addressing common questions about the Generation 4 Glock pistols. Key topics include the discontinuation of OD green frames, the evolution of the recoil spring system to resolve early 9mm reliability issues, the benefits of the Modular Backstrap System (MBS), and a specific reassembly tip for Gen 4 models. The discussion also touches on the continued production of Gen 3 models and the discontinuation of the RTF2 finish.

Quick Summary

Glock's Mike McAvoy addressed Gen 4 reliability issues at SHOT Show 2011, explaining that early 9mm cycling problems were due to the recoil spring assembly's .40 S&W origin. A lighter 9mm-specific spring was released. He also detailed the Modular Backstrap System (MBS) for customizable grip size and confirmed continued Gen 3 production.

Frequently Asked Questions

What were the main reliability concerns with early Glock Gen 4 9mm pistols?

Early Glock Gen 4 9mm models sometimes experienced cycling issues, particularly with lower-pressure ammunition or when subjected to 'limp-wristing'. This was attributed to the dual recoil spring assembly initially being designed for the .40 S&W caliber. Glock later released a lighter recoil spring specifically for the 9mm Gen 4 pistols to resolve these issues.

How does the Glock Gen 4's Modular Backstrap System (MBS) work?

The MBS allows users to customize the grip size of their Gen 4 Glock. The pistol comes with interchangeable backstraps that easily snap onto the rear of the frame, enabling adjustments from a 'Short Frame' size to Medium (similar to Gen 3) or Large, improving ergonomics for various hand sizes.

Will Glock continue to produce Gen 3 models alongside Gen 4?

Yes, Glock confirmed at SHOT Show 2011 that Gen 3 models would continue to be manufactured concurrently with the newer Gen 4 versions. This provides consumers with options based on their preference for features and design.

What is the purpose of the beaver tail backstrap on some Glock Gen 4 models?

The snap-on beaver tail backstrap accessory for Glock Gen 4 models is designed to prevent 'slide bite,' a common issue where the slide can pinch the shooter's hand, especially those with larger hands or a high grip. It provides a more comfortable shooting experience.
