Speer
Uni-Cor bonded-core 200gr JHP at 1,100 fps. Speer's defensive 10mm runs slightly under the Federal HST in velocity but delivers bonded-core barrier performance and is widely available at a similar price point.
Speer Gold Dot 10mm 200gr is the bonded-core defensive alternative to Federal HST. At 1,100 fps and 537 ft-lbs, it runs a touch under the HST 200gr in raw velocity, but the Uni-Cor electrochemically bonded jacket and core construction is the Gold Dot's primary edge: the jacket cannot separate from the core through any practical barrier, which keeps the bullet driving straight and retaining mass through auto glass, wallboard, and heavy clothing.
Gold Dot has been a #1 or #2 law enforcement choice across calibers for decades, with thousands of documented real-world shootings backing up the design. In 10mm, the 200gr Gold Dot delivers consistent expansion in the 0.60-0.70 inch range with penetration in the 14-17 inch FBI window. It's slightly less expansive than the Federal HST but more consistent through barriers, which makes it the preferred pick for shooters who anticipate vehicle barriers or harder intermediate obstacles.
For shooters who already run Gold Dot in their 9mm or .45 ACP carry guns and want to standardize on the same defensive design across the safe, this is the obvious 10mm pick. Cycle-tested and street-proven, it's a load you can carry with full confidence in a Glock 20, M&P 10mm, or any duty-class 10mm pistol.
Add the Speer Gold Dot 10mm 200gr JHP to your build and see how it enhances your platform.
