Okay, I just set up the masked P1 I bought last night, and BUMMER -- I think there's an important part from the backpack missing: the part where the arm of the shoulder cannon goes into.
From the pictures I never thought that it could get off of the backpack. My figure's facory sealed, and I looked all over, from the box to every part of my room, and it's not there.
I don't think I could have it replaced as I was lucky enough to get the last P1 piece among a lot of P2s.
I ended up improvising, cutting a part of the cannon arm and supergluing it on to the backpack. The cannon can't retract and is closer to the dreads but better than not having it there at all.
Will post pics when I can.
Edit: I think my visor seems to have little gap compared to what I've seen on the pictures (including the ones on the box) though. Having no time/resources to do lens mod I thought of applying a coat of clear nail polish on it, and now it's glossy enough to my liking
