Frequently Asked Questions

How do different handgun calibers perform when shooting through a car windshield?

In tests with 9mm, .40 S&W, and .45 ACP, all calibers penetrated a laminated automotive windshield from 6 yards. The 9mm showed a slight drop, while the .40 S&W and .45 ACP had minimal drop and caused significant glass displacement, leading to secondary impacts on the target.

What type of glass is used in car windshields for ballistics testing?

Automotive windshields typically use laminated glass. This type of safety glass consists of two layers of glass with a plastic interlayer, designed to hold together when shattered, which was a key material consideration in this penetration test.

Does bullet drop increase when shooting through a windshield at an angle?

During this test, bullet drop was minimal when shooting through a laminated windshield at an angle. The 9mm round showed a slight drop of about 2 inches, while the .40 S&W and .45 ACP rounds exhibited negligible drop, indicating the windshield had little effect on trajectory over this short distance.

What firearms were used in the windshield penetration test?

The test featured a Glock 19 chambered in 9mm, a Glock 27 in .40 S&W, and a Sig Sauer P220 in .45 ACP. All firearms were loaded with hollow point ammunition for the penetration test.
