Frequently Asked Questions

What were the initial reliability issues with the Glock Gen 4 9mm models?

The initial Gen 4 9mm Glocks used a dual recoil spring assembly designed for the .40 S&W caliber. This could lead to cycling problems, especially with low-pressure ammunition or when the shooter 'limp-wristed' the firearm, causing failures to feed or eject.

How did Glock address the Gen 4 9mm reliability concerns?

Glock resolved the reliability issues by releasing a lighter, specifically designed recoil spring assembly for the Gen 4 9mm pistols. This new spring corrected the cycling problems experienced with certain ammunition types and shooting techniques.

What are the key ergonomic upgrades in the Glock Gen 4 pistols?

Gen 4 Glocks feature a larger, reversible magazine release for ambidextrous use and the Modular Backstrap System (MBS). MBS allows users to swap out grip panels to adjust the frame size for a more personalized and comfortable fit.

Can I still buy Glock Gen 3 pistols?

Yes, Glock confirmed at SHOT Show 2011 that Gen 3 models would continue to be manufactured alongside the newer Gen 4 versions. However, the RTF2 (Rough Texture Finish) models were discontinued as the Gen 4 grip offered a similar texture.
