Duration: 4:06

This review details the installation and performance testing of a KKM Precision 6-inch barrel on a Glock 20C chambered in 10mm Auto. The video demonstrates the barrel swap, compares the 10mm cartridge to .40 S&W, and showcases terminal ballistics tests. The presenter, Matt from Demolition Ranch, provides an experienced assessment of the modification's impact on shooting performance and projectile energy.

Quick Summary

The KKM Precision 6-inch barrel for the Glock 20C 10mm is designed to increase muzzle velocity and ballistic performance. While the ported factory barrel offers significant muzzle flip reduction, the extended KKM barrel may alter the point of aim, requiring potential sight adjustments. Terminal ballistics tests show the 10mm cartridge delivers greater penetration and energy than the .40 S&W.

Frequently Asked Questions

What are the benefits of a 6-inch barrel on a Glock 20C 10mm?

A 6-inch barrel, like the KKM Precision model, is intended to increase the muzzle velocity of the 10mm cartridge. This can lead to improved ballistic performance and potentially greater energy transfer downrange, though it may also affect the firearm's handling and point of aim.

How does the 10mm cartridge compare to the .40 S&W in terms of recoil and ballistics?

Visually, the 10mm is a larger cartridge than the .40 S&W. While a ported barrel can mitigate muzzle flip for the 10mm, terminal ballistics tests show the 10mm creates larger exit holes and demonstrates greater penetration, indicating more energy.

Can changing the barrel on a Glock 20C affect its point of aim?

Yes, installing an aftermarket barrel, such as the KKM 6-inch barrel, can alter the firearm's point of aim. The presenter noted shooting high and right after installing the new barrel, suggesting a need for potential sight adjustments or familiarization.

What are the key features of the KKM Precision 6-inch barrel for the Glock 20C?

The KKM Precision 6-inch barrel is an unported, stainless steel barrel specifically designed for the 10mm caliber Glock 20. Its extended length is intended to optimize ballistic performance by increasing projectile velocity.
