now, if only he came with a pump-action shotgun (or I had the conversion skill to model one on!), I'd be a very happy man!

Smith...

by the way (off topic)

Love your avatar pic.  I just went to two weeks ago to see a late-night BTILC rescreening in a movie theatre, it was incredible.

What about this. Copplestone Castings, KKBB, Soul Section.
Middle guy has a pump action. Maybe a simple head swap or some putty work to lose the beret.

That's your paint work there, Steve? Very nice.

Oh, no, alas!  I pinched the photo from the Gripping Beast web-site whose URL I gave.

That is a nice figure, just wish the breech was closed and it was at his shoulder.

The Pulp Boys in Blue actually come wiht weapon options. That pump-action shotgun can be substituted leaving you with the spare weapon and hand.
