Frequently Asked Questions

Can inexpensive safety glasses stop 9mm fragments?

Yes, the test showed that even budget safety glasses, costing around $3, successfully stopped high-velocity 9mm fragments from penetrating the lenses, although some cheaper frames cracked under impact.

What is the CAA MCK?

The CAA MCK (Micro Conversion Kit) is an accessory that converts compatible Glock handguns into a pistol carbine-like platform, featuring a folding brace, integrated flashlight mount, and a spare magazine holder.

How effective are safety glasses against ballistic fragments?

Safety glasses are highly effective at preventing penetration from ballistic fragments. Even when fragments embed deeply into the lens, they are stopped, protecting the wearer's eyes from serious injury.

What happens to safety glasses when hit by fragments?

When struck by fragments, safety glasses typically show significant pitting and impact marks. While the polycarbonate lenses usually prevent penetration, the frames, especially on cheaper models, may crack or break.
