Pachmayr revolver speedloaders will set the standard for quality and performance. Unlike competitive models which are made of plastic, Pachmayr speedloaders are precision CNC machined from solid aluminum. The speedloader bodies are cut in a polygon shape which produces the smallest possible outside dimensions and allows them to easily fit compact revolvers. The speedloaders are also equipped with a rattle eliminating o-ring which contacts the cartridge bases and firmly holds the rounds in place. Cartridges are released with a simple twist of the large knurled knob.
