Well i'm guna take it apart or use my friends bore scope to try and verify what piston is in it. Honestly i kinda hope that it's not a 330 cus from the little bit I've read it sounds difficult to get replacement pistons and such. I didn't get hurt either way, i only had $325 in the handgun i traded... i can part the thing out for more than that!

Thanks for the input though guys, guess i need to figure out what i got for sure before anyone can advise any further
