Speer 165 Grain Jacketed Hollow-Point (JHP) Ammo Details

Speer’s Law Enforcement ammunition is designed to give professionals the barrier blind performance they can’t do without to stay safer while on duty. This 40 S&W cartridge’s 165 grain Gold Dot projectile manages that because it is core and jacket are bonded together electrochemically, making them nigh inseparable as the bullet passes through a variety of urban barriers. This bullet burrows through heavy clothing, wall board, and plywood without losing virtually any of its weight -- even safety glass hardly puts a damper on a Gold Dot’s superior weight retention.

The Gold Dot is formed over the course of a two-stage process. In the first, the width to which it can expand is established. In the second, the rate of its expansion is predetermined. As the result a Gold Dot dependably delivers lethal terminal performance that you can bank on to keep your hide in one piece, just like it belongs. Furthermore, because this bullet’s jacket was formed one molecule at a time it’s intensely concentric for assured straight flight.

This cartridge features a nickel plated brass casing. Nickel reduces friction to ensure uninterrupted cycling, and also resists corrosion so that exposure to atmospheric moisture won’t compromise your self-defense load’s potency.

Ballistic Gel Testing


We tested this Speer 40 Smith & Wesson ammo by firing five rounds with a S&W M&P40c with a 3.5-inch barrel into calibrated Clear Ballistics gelatin. Of those five rounds, we discovered the ammo penetrated an average of 15.88-inches into the gelatin. Our test rounds ended the test with an average expanded diameter of 0.618-inches, retaining 100% of the projectile's original weight.
