I just bought this Gas BlowBack Pistol (GBBP) last Thursday from Toronto Airsoft (www.torontoairsoft.com). Here are all the bits and pieces to it~

Silencer; extended barrel (for the silencer); pistol; magazines.

The pistol only came with one mag (the all-black metal one on the right), so I bought a spare.

The gun runs on Green Gas or CO2 (if I remember correctly), so I have a can of GG ready to go.
