Speer 155 Grain Jacketed Hollow-Point (JHP) Ammo Details

This is 40 S&W Speer Law Enforcement Gold Dot 155gr. Hollow Point Ammo. Speer Gold Dot Ammunition is designed to deliver the high performance today’s law enforcement officers demand. Each Gold Dot bullet is individually engineered to provide shot-to-shot uniformity and ensure optimum wounding when fired through a variety of barriers. The result is a cartridge that provides officers the ultimate defense in lethal force confrontations. Jacket/core separations are the main cause of bullet failure and a real problem for traditional lead-core, jacketed hollow point bullets. Most bullets perform adequately in soft tissue, but fragment or expand prematurely when obstructed by bone, heavy clothing or any number of other potential real life shooting barriers. Why? Because conventional bullets are made by forcing a lead core into a jacket creating a two-piece bullet design. Gold Dot was the first handgun ammunition to be loaded with high-performance bonded core bullets. SPEER’S superior Uni-Cor process bonds the jacket to the core one molecule at a time, virtually eliminating core jacket separations. That’s why SPEER Gold Dot is the #1 choice for Law Enforcement Professionals. This is current production ammunition, packed in 50rd. box.

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.

    I tested this load side by side with Winchester 155gr. Silvertips, Winchester Ranger 155gr. JHP's, and Hornady 165gr. Critical Defense from my short barreled Glock 27. All loads expanded in wet newspaper and in water despite the short barrel length of the 27. The Gold Dot was second in penetration to the Hornady. The jackets separated in both Winchester loads but the Gold Dot & Hornady loads held together. The Gold Dot had the most devastating effect on the wet newspaper. It was awesome compared to the other loads. On targets, it is very accurate.<br />

    All the loads I mentioned performed well from my G27. The Critical Defense gave the deepest penetration, the Winchesters gave the most expansion, but the Gold Dot did the most damage to the newspaper and is my overall favorite.

    This is my first choice in .40 gold dot loads. It is accurate and performs well through barriers. Also for me this load has the lowest recoil out of the three in my G27 and shoots straight so thats what I feed it. I shoot alot of 9mm glocks also and I've found that this load(many 155s) shoots to a very similar POA as my 9mms so i dont have to make any compensation when switching, one less thing to think about.

    Out of my 4" barrel XD and into water jugs only, then with 2 layers denim, and then with 4 layers of denim, the expansion was consistently impressive. The 4 layer denim test is the true test of a hollow-point to expand well under most all conditions. (it would be a better test in to ballistics gel, but I did not have any). This is my defense load of choice in the .40.

    This is the best bonded 155gr ammo for your .40 that you can get. The muzzle velocity and kenetic energy make for a devistating wound channel. My ballistic testing showed great penetration and expansion out of a Glock 22. Recoil and muzzle flip was very controlable.
