Look at this Pancreator-lovin' gun. Is this not awesome?
This is the X-Power Shock Blaster from Simba. While everyone's ooh-ing and ah-ing over Nerf guns, Simba snuck out this freaking bolt pistol lookielike
And you see that open bullet chamber? That's right; once the dart's fired you cock it again and the freaking shell casing tinkles onto the ground.
OK, so it's not what you's want in a forest shooting match, but in a closed social environment it just looks funky. Plus, spent cartridges are a storytelling device. They say 'there was a fight here' without having to do messy special effects and make someone lie still for too long.
I picked it up in Toymaster for £12, down from £16. It isn't coming up any more, but Amazon and other places have them.
