9mm vs 40 S&W -Let's not discount the 40 S&W yet...

A few years back, all the magazine articles told us how superior the 40 S&W was to the 9mm Luger. More recently the stories have flip flopped. So, we decided on some unbiased at home tests.

Today, it was bullet proof plexiglass. We kept ammo as equal as possible. No silly games like FMJ vs Frangible, etc. Ammo was same brand, bullet style, equivalent weight 9mm 124 grn vs 40 155 grn, etc. Then away we went.

This particular test was with Hollow Point XTPs.

Shot at 7 yards and repeated several times with consistent results.

100% of the time, the 40 S&W penetrated straight and true. The 9mm tried to deflect and stopped sideways.

The next view is the best picture I could get from the side. Again, the superior penetration of the 40 S&W (Left) was undisputable.

I can't speak for all ammo types. But we tried several and the results were consistent.
