i would say there is no slam fire, I also say does anyone understand how the disk mag works, I have not the slightest clue.
The magazine is pretty much a vertical version of an airsoft "Gas Grenade" launcher, revolving chamber. You add discs until one chamber is full and then you prime the spring and move the next empty chamber into loading position with the toggle on the top of the magazine. When the chamber is empty during fire it rotates to the next full chamber and because you have discs in the top magazine above the chambers, you will not have a pause in ammunition supply. Very clever design and as soon as it hits the shelves here in Aus, I am getting one; Praxis be damned :P.
He's not using slamfire
He is, though very slowly. Look at his trigger finger. It doesn't move at all yet the blaster fires.
I don't think he used it, but that doesn't mean it can't slamfire. Maybe he never tried.
For anyone whos having connection problems, I've upload this video and the other two and youtube.http://www.youtube.com/user/BasicNerf/videos
