I think the only thing you need to be concerned about is if you plan to fire the pistol a lot. If you do a lot of shooting, firing the heavier 9mm Luger/Parabellum bullets will batter the aluminum alloy frame. Cracks in the frames were reported by police agencies that shot a lot. Walther upgraded the pistol to the P4, which had a hexagonal cross-bolt to absorb recoil forces. But before you have any kind of problem, you'd have to do really a lot of shooting with it. I had one when I lived in the US, shot it only occasionally (used 115 gr. bullets), and never had a problem. I like the gun.
