for trade?

I'm considering to sell my MGC super black heavyweight Colt Python 357 revolver 4", because I'm a pistol-man,
but I prefer to trade this revolver for a tanaka glock 18 with railed frame (so the gen. 3, not the gen. 2).

It's in absolute perfect condition with 2 packs of cartridges included. The box is also included.
For a picture of mine, please see page 2 of this thread:
