WIP: Hammershot / Hammerick / Mavershot

I decided that I wanted to make a nicer version of my old sidearm ( hoellenhamster.deviantart.com/… ) even though I am pretty happy with it. This is just such a satisfying mod. Since I was asked about the handle a couple of times before I thought it might be helpful to post a WIP shot of this - see the large blob of yellow/greenish stuff on the handle? That is where you should reinforce the handle from the inside prior to sanding the faux-bandage down.
The front is taken from an old Maverick, all the white pieces are plastic sheet, the beige stuff is polyester putty and the yellow/greenish stuff is Milliput (epoxy putty).
I am very much open to suggestions - if you have a cool idea (that I like) and you comment before I paint this I might add it to the design (and give you credit for whatever the idea was^^).

Regards
