This video from CF Clips, featuring insights from Kaya E. of Classic Firearms, analyzes the recoil spring design changes in Glock pistols. It highlights the shift from the dual-stage assembly in Gen 4/5 models back to a single-stage polymer rod design in the Gen 6, reminiscent of Gen 2/3 models, indicating extensive testing by Glock on this older design.

Quick Summary

Glock Gen 6 pistols feature a single-stage polymer rod recoil spring, a return to the design used in Gen 2 and Gen 3 models. This contrasts with the dual-stage recoil spring assemblies found in Gen 4 and Gen 5 Glocks, suggesting Glock has extensively tested and validated this 'old school' design for their latest generation.

Frequently Asked Questions

What is the main difference between Glock Gen 4/5 and Gen 6 recoil springs?

Glock Gen 4 and Gen 5 pistols feature a dual-stage recoil spring assembly. In contrast, the Glock Gen 6 reverts to a simpler, single-stage polymer rod design, similar to what was used in older Gen 2 and Gen 3 models.

Why did Glock change the recoil spring design for the Gen 6?

While the video suggests a 'backward' step, it implies Glock has extensively tested the single-stage polymer rod design for the Gen 6. This indicates a deliberate choice, possibly for reliability, cost, or performance optimization based on their testing.

What does the dual-stage recoil spring in Glock Gen 4/5 do?

The dual-stage recoil spring assembly in Glock Gen 4 and Gen 5 models is designed to manage recoil in two distinct phases during the firing cycle, potentially offering a smoother shooting experience compared to single-stage designs.
