Ballistic Gel Testing
In hopes of giving ourselves and our customers a better idea how this 40 Smith & Wesson self-defense ammo would perform if called upon in a self-defense scenario, we tested dozens of the best selling hollow points on the market.
We fired five rounds of this Speer 40 Smith & Wesson ammo through a cloth barrier into Clear Ballistics calibrated synthetic gelatin and recorded the results. For these tests, we used a S&W M&P40c with a 3.5-inch barrel. In the photos, graphics and video on this page, you can see specifically how the Speer ammo performed and how it sticks up with the rest of the 40 Smith & Wesson ammo we have tested so far.
