Duration: 10:13

This review compares the Glock 20 SF and Glock 29 SF in 10mm, focusing on velocity and terminal ballistics. The Glock 20 offers higher velocity due to its longer barrel, while the Glock 29 is more concealable. A massive gel test demonstrated the extreme penetration of Underwood 220gr Hard Cast, making it suitable for large animal defense.

Quick Summary

The Glock 20 SF is better for trail use due to its higher capacity (15+1) and shootability, while the Glock 29 SF is a viable concealed carry 10mm option. A gel test showed Underwood 220gr Hard Cast ammo from the G20 achieved over 62.5 inches of penetration, ideal for bear defense.

Frequently Asked Questions

What is the main difference between the Glock 20 SF and Glock 29 SF for 10mm performance?

The primary difference impacting performance is barrel length. The Glock 20 SF has a longer barrel (4.61 inches) which yields higher velocities, while the Glock 29 SF has a shorter barrel (3.77 inches) making it more concealable but with slightly reduced velocity.

Which 10mm Glock is better for bear defense based on the gel test?

For large animal defense like bears, the Glock 20 SF paired with heavy, hard-cast loads like the Underwood 220gr Hard Cast is recommended due to its extreme penetration capabilities, exceeding 62.5 inches in ballistic gel.

Is the Glock 29 SF a good option for concealed carry in 10mm?

Yes, the Glock 29 SF is presented as a viable concealed carry option for the 10mm caliber. Its compact size and reduced grip length make it more manageable for discreet carry compared to the larger Glock 20 SF.

How does barrel length affect 10mm velocity between the Glock 20 and Glock 29?

The Glock 20's longer barrel consistently produced higher velocities across various 10mm loads tested. This difference is directly attributable to the increased distance the bullet travels within the barrel, allowing more powder to burn and accelerate the projectile.
