The Speer 4397 Gold Dot Personal Protection ammunition delivers proven stopping power for 40 S&W firearms with its 165-grain jacketed hollow point design. This premium defensive ammunition features Speer's patented Uni-Cor construction that bonds the jacket to the core, preventing separation upon impact for maximum weight retention and consistent expansion.
What Makes This Different
Unlike standard hollow point ammunition that can suffer jacket separation, Gold Dot bullets use a proprietary electrochemical bonding process that fuses the jacket molecularly to the lead core. This construction ensures the bullet retains 95% or more of its original weight through barriers like heavy clothing, wallboard, and auto glass. The result is deeper penetration with controlled expansion that meets FBI protocol standards for law enforcement ammunition.Key Features
