took a shot, and heard a *ting* which I thought was just a steel gong, cycled it again, and it felt a little gritty, but it was gritty straight outta the box, so fired again, heard the sound like a hammer hitting an anvil, tried to cycle it and it wouldnt... started to unload the remaining shells, and a few bits of metal fell out the bottom.
when I got it home and disassembled it, the slide block was in 6 pieces, which is where the metal came from. That was rounds 26 and 27 through it, that caused it to die.
I also managed to slice my finger wide open while disassembling it, on the slide rails, mine was apparently made out of recycled razors.
