Details, The Maruzen P99 is a very good replica of the Walther P99. The performance is not bad at all and the kick is really nice and it's an original pistol, James Bond fans must have! This pistol has no external hammer, but it works like a double/single action pistol. The button on the slide allows to decock the gun. This has a plastic grip and a plastic slide, so will work better with abbey ultragas/144a gas. You MUST be 18 or over to purchase this product.
