Strike Industries’ Enhanced Pin Kit for Glock features an anti-walk locking block pin. Designed for the serious user in mind the high strength steel pins are upgraded for better serviceability and function. The anti-walk locking block pin engages the slide stop lever spring in a similar way to the trigger pin to help prevent walk out. The ends of the pins are concave to support a pin punch prevent slippage and mitigate potential damage. The trigger/locking block pins are constructed of carbon steel with a black nitride finish while the trigger housing pin is constructed of aluminum with a black anodized finish. The pins can be color-filled to add another degree of customization (not included).
