This video provides an expert-level comparison of handgun calibers, focusing on 9mm and 10mm, from the perspective of a seasoned firearms instructor. It details practical tests including recoil management, follow-up shot speed using a shot timer, penetration tests with flour bags, and terminal ballistics in Clear Ballistics gel. The instructor concludes that 10mm is a highly versatile caliber suitable for various defense scenarios, manageable for experienced shooters.

Quick Summary

Expert firearms instructor compares 9mm and 10mm calibers using ballistics gel, penetration tests, and shot timers. The 10mm offers superior power and penetration for demanding scenarios, while 9mm remains an economical and manageable choice for general self-defense. Follow-up shot speeds can be surprisingly similar between the two.

Frequently Asked Questions

What is the primary advantage of the 10mm handgun caliber compared to 9mm?

The 10mm Auto caliber offers significantly greater power, penetration, and potential for creating a larger wound cavity than the 9mm. This makes it a more formidable choice for scenarios requiring higher energy transfer, such as defense against larger threats or animals.

How does recoil differ between 9mm and 10mm handguns like the Glock 17 and Glock 20?

While 10mm generally has more recoil than 9mm, the larger frame size of firearms like the Glock 20 effectively mitigates much of this perceived recoil and 'snappiness', making it manageable for experienced shooters.

Can follow-up shot speed be maintained when shooting 10mm compared to 9mm?

Yes, objective testing using a shot timer shows that follow-up shot speeds can be nearly identical between 9mm and 10mm in comparable firearms, with both achieving around 1 second for three shots, though 9mm may feel subjectively more controllable.

What testing methods were used to compare the effectiveness of 9mm and 10mm ammunition?

The video employed multiple testing methods, including penetration tests using bags of flour, terminal ballistics analysis in Clear Ballistics gel to measure wound cavity and penetration depth, and shot timer drills to compare follow-up shot speeds.
