Its patented transfer bar mechanism provides an unparalleled measure of security, while the integrated sub-assemblies allows for easy maintenance and assembly. The grip frame design easily accommodates a wide variety of custom grips. Includes three full moon clips that act as both a speed loader for the 10mm rounds and aid in the ejection of the spent cartridges.
