No, this buy is long dead. Due to RSR's inability to deliver and they raised their wholesale price. Since I have no idea if/when they will ever come in, you would be better off to surf ebay because those sellers seem to be the only ones that can get them.
The Walther laser is made in China. They are rated Class IIIA at a wavelength of 635 nm. A drop of Blue Loctite in the Windage / Elevation worm screws will help keep zero forever, while allowing re-adjustments (rarely needed).
Fine at dawn/dusk and on a heavily overcast day. The laser makes the P22-shooter shoot straight, with little effort. By far the best addition to a P22, save a muzzle can.
