This is waaaay off topic, but any of you who might have a Walther P22 should know about this.
I just bought a Viridian Laser sight for a P22 I haven't even taken delivery on yet.

These are amazing sights and way ahead of the ones Walther sells.
The green laser is even marginally visible on direct sunlit snow at 30 ft.!!!
The company is still (I think) honoring a special $189 (regular $250) price given in the Dec. issue of Guns & Ammo.
