Regardless of what its made of, Mine is accurate, and reliable. The sights were perfect right out of the box. The barrel is threaded, and uses the same adapter the P22 uses. The Double Action trigger pull is horrible. Single Action is nice, and crisp. Magazines are hard to find. I have close to 2,000 rounds thru mine now, very, very few malfunctions, if any, and I see no signs of wear. Are there better pistols available for the same money? Yes. Have I enjoyed owning, and shooting my Walther/Umarex PPK/S? Yes.
