Speer Gold Dot 5.7×28mm 40gr GDHP — 500 Rounds

The Speer Gold Dot 5.7x28mm 25728GD is the first purpose-designed civilian defensive load for the 5.7×28mm cartridge.

A 40-grain Uni-Cor bonded hollow point at 1,800 fps and 288 ft-lbs, built with the same Gold Dot construction trusted by law enforcement worldwide.

At $1.70 per round for 500 rounds, this is the premium defensive tier in the 5.7×28mm category.

First Purpose-Built Civilian Defensive 5.7×28mm

The 5.7×28mm cartridge was developed by FN for military and law enforcement platforms.

FNH’s duty loads (SS190, SS198LF, SS195LF) were designed for law enforcement and military use, or as lead-free training rounds — not civilian defensive carry.

When civilian versions of the Five-seveN and the Ruger-57 arrived in the commercial market, there was no hollow point load specifically engineered for civilian defensive use.

The Speer Gold Dot 5.7x28mm 25728GD filled that gap — the first 5.7×28mm ammunition specifically designed and marketed for personal protection.

Uni-Cor Bonding in 5.7×28mm

Gold Dot uses Speer’s Uni-Cor electrochemical bonding process — the jacket is applied to the lead core one atom at a time, creating a true metallurgical bond rather than a mechanical or adhesive interface.

The result: core and jacket stay together through barrier penetration. The Speer Gold Dot 5.7x28mm is engineered to perform consistently through all common barriers — glass, denim, wallboard — at the 1,800 fps velocity of the 5.7×28mm platform.

40 Grains — The Defensive Weight Class

At 40 grains, this matches the Federal American Eagle AE5728 TMJ (range/training, 1,655 fps).

Running AE5728 at the range and Speer Gold Dot 5.7x28mm for carry confirms function and builds trigger time with the same bullet weight as the defensive load.

The two-stage hollow point cavity formation — the first stage sets expansion diameter, the second controls expansion rate — is the same patented cavity design used across the Gold Dot pistol line.

Nickel-Plated Brass

Nickel-plated brass feeds smoothly through the delayed blowback action of the Five-seveN and Ruger-57, and resists corrosion during extended carry.

Frequently Asked Questions

Is the Gold Dot really the first civilian defensive 5.7×28mm load? At its launch, yes — Speer’s 25728GD was the first 5.7×28mm hollow point designed and marketed specifically for civilian personal protection. The FNH load variants (SS190, SS197SR, SS198LF, SS195LF) were designed for military, law enforcement, or training use. The Gold Dot brought standard defensive load engineering — Uni-Cor bonding, two-stage cavity, controlled expansion — to the 5.7×28mm platform for the first time.

What is Uni-Cor bonding? Speer’s electrochemical process that deposits jacket material one atom at a time directly onto the lead core. This creates a true metallurgical bond — stronger than mechanical crimping or adhesive — so the jacket stays on the core through barrier penetration and velocity extremes.

How does the Gold Dot compare to the FNH training loads in this category? The FNH training loads (SS198LF green tip, SS195LF blue tip) are 27-grain lead-free rounds at 2,050–2,480 fps, positioned for training and indoor ranges. The Gold Dot 40gr is the defensive load at 1,800 fps — heavier, slower, with bonded hollow point construction for controlled expansion on target. Not the same application.

Why use the Federal AE 40gr TMJ for range training instead of this? Cost and lead-free indoor range compliance. The AE5728 TMJ runs $1.18/round vs $1.70/round for Gold Dot, and its TMJ construction reduces lead vapor at indoor ranges. Matching bullet weight (both 40gr) means training recoil characteristics closely mirror the carry load.

What platforms chamber 5.7×28mm? FN Five-seveN pistol, FN PS90 carbine, Ruger-57 pistol. Confirm your specific platform before ordering.

Is it lead-free? No — standard lead core with Uni-Cor bonded copper jacket.

How many rounds is 500? 10 × 50-round boxes.

What’s the per-round cost? $849 / 500 = $1.698 per round.
