I bought a cheap double barrel shotgun toy from Toys'R'Us. It was pretty undersized with the barrel and stock. So I cut the barrel to a sawn off and removed the stock and it ended up being a pretty good size. I still wanted to beef up the receiver and shape the grip. I used cardboard and canvas for bulking out the receiver and shaped the grip with bondo. Bondo on the receiver and a cut piece of plastic helped modernise and cover some of the imperfections even if bondoing straight lines was pretty difficult. I painted it in stages, finishing the grip end first, spraying on primer to see if there were any imperfections to fix. The break mechanism should have been a latch, but that would have been too difficult to change, so I stuck with the regular button on the toy. With the back half done, I worked on the grip. Taking a piece of plastic cut from a Roses lid, I heat shaped the curved grip and bondoed imperfections. I felt the grip looked too thick at this stage especially underneath. I shaved off the bulk of the bottom of the grip and reapplied bondo before moving onto the primer coat. Next came painting. I used a metalcote paint for the gunmetal which gives off a metal finish when polished and the wood grain was painted in layers with a coarse paintbrush, the brushstrokes giving the grain effect, before being hit with a glossy laquer. Thankfully, the break action still works after all that painting.
