Designed for USPSA's demanding "Limited Division" this variation of our most-popular floorplate is machined from brass bar to add weight (five ounces of it) along with capacity. Like the original, it 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 you a custom-made Wolff. Additional springs are available under "springs and misc." NOTE: Using brass +5 basepads will accelerate the wear on your magazines. We suggest leaving the brass basepads on, and only cleaning the interior of the magazine occasionally (many people grossly over-clean their Glock magazines -- while appropriate for some guns, constant cleaning isn't necessary on the Glock). Because these basepads are much heavier than stock, keep an eye on your magazine catch notch. Though we haven't experienced it, additional wear has been reported. 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.
