Pachmayr's revolver Speedloader sets the standard for quality and performance. Unlike competitive models which are made of plastic, Pachmayr's Speedloader is precision CNC machined from solid aluminum. The body is cut in a polygon shape which produces the smallest possible outside dimensions and allows them to easily fit compact revolvers. The Speedloader is 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.Pachmayr's new revolver Speedloaders will set the standard for quality and performance.
