The Speer Gold Dot .357 SIG 125gr load is a 20-round box of self-defense handgun ammunition (Speer part no. 23918GD). Each cartridge carries a 125-grain Gold Dot hollow point bullet that Speer rates at 1350 fps from a 4-inch test barrel. Speer describes the original Gold Dot line as a benchmark for both self-defense and duty use, trusted by law enforcement world-wide. The bullet has a pressure-formed lead core bonded to an extremely uniform jacket one atom at a time, which Speer says virtually eliminates separation on impact for more retained weight and penetration. The hollow-point design is built to expand consistently through the full range of barriers, and the cartridge is loaded in nickel-plated brass with a sealed primer.
