Duration: 9:39

This guide details a head-to-head ballistic gel test comparing 9mm Luger +P and .40 S&W ammunition, as demonstrated by an experienced firearms reviewer. The test involved firing specific loads through denim barriers into gel blocks, measuring velocity and penetration, and analyzing recovered projectiles. The .40 S&W HST showed more dramatic expansion, while the 9mm +P achieved deeper penetration. The comparison highlights trade-offs between terminal performance, capacity, and recoil in compact firearms.

Quick Summary

An experienced firearms reviewer compared 9mm +P and .40 S&W using ballistic gel. The 9mm +P (124gr Gold Dot) penetrated deeper (18 inches) at higher velocity (1109.5 fps), while the .40 S&W (180gr HST) expanded more dramatically but penetrated less (14 inches) at 965.5 fps.

Frequently Asked Questions

How does 9mm Luger +P compare to .40 S&W in ballistic gel tests?

In a ballistic gel test, 9mm Luger +P (124gr Speer Gold Dot) achieved deeper penetration (approx. 18 inches) with velocities around 1109.5 fps. The .40 S&W (180gr Federal HST) showed more dramatic expansion but less penetration (approx. 14 inches) with velocities around 965.5 fps.

What are the key differences in terminal ballistics between 9mm and .40 S&W?

Terminal ballistics differ based on ammunition. The .40 S&W often offers wider expansion, while 9mm, especially +P loads, can achieve greater penetration. Factors like bullet weight, design, and velocity significantly influence performance in ballistic media.

Which firearm was used for the 9mm testing in the ballistic gel comparison?

For the 9mm testing, a Smith & Wesson 3913 pistol was utilized. This was chosen alongside a Glock 29 (with an aftermarket .40 S&W barrel) to ensure comparable barrel lengths for a fair comparison of the calibers' performance.

What ammunition loads were compared in the 9mm vs .40 S&W ballistic gel test?

The test compared Federal Premium 180 grain HST for .40 S&W and Speer Gold Dot 124 grain +P for 9mm Luger. These specific loads were selected to represent common duty or self-defense ammunition for each caliber.
