The Armaspec Pin Set for Glock Gen4 (brand part number ARM143-SS) is a stainless steel three-pin set covering the trigger pin, locking block pin, and ejector housing pin. Replacing all three at once during a detail strip or a refresh gives a Gen4 Glock a full set of corrosion-resistant stainless pins instead of mixing a worn factory pin with a new one. Armaspec cuts the set for a broad range of Gen4 frames, covering the Glock 17, 19, 20, 21, 22, 23, 26, 27, 34, 35, 37, 38, and 39.
