If you prefer your firearms in the handgun variety, Nyko has come up with a third-party gun peripheral for the Wii to use as an alternative to the recently released Wii Zapper.
Unlike the Wii Zapper, which holds both the Wii Remote and the Nunchuk for a two handed gun experience, Nyko’s Perfect Shot only holds the remote. It does however allow you to hook the Nunchuk into it but you would still be holding it in your other hand. Some people may prefer it this way though.
Club Skill has a few images of the Perfect Shot including the one below. It will go on sale in December for about 15 bucks.
