Designed for USPSA's demanding "Limited Division" our 140mm provides +3 rounds of .45, with rock-solid retention and security. New "black magic" retainer allows quick disassembly. Just loosen the two screws and the locking plate pivots out of the way. Package ships with custom spring. Additional springs are available under "springs and misc." Due to U.S. State Department restrictions, we cannot ship this part internationally.
