Designed for USPSA's demanding "Limited Division" this basepad provides up to +5 rounds of .40, +6 rounds of 9mm, with rock-solid retention and security. Requires an extended spiring (either Wolff or ISMI). We ship a custom Wolff along with it. Additional springs are available under "springs and misc." NOTE: There are at least five factory Glock magazine body variants, and roughly 11 followers for the 9mm alone. Some combinations will provide only +5+ in 9mm, or +4+ in .40. Due to U.S. State Department restrictions, we cannot ship this part internationally.
