Sweet, thanks for the feedback gang. Here's a bit of an update of what the grip looks like:

This is the back section + the body of the gun. Here's what I've got planned:
Left - remove excess material to create two notches to fit into holes of body
Right - remove square notches for the grip notches to go into

This is what the front section looks like. Notice the red U's I've highlighted, as they are equal in size, and the grip doesn't seem to have excess material for it to be shaved down so that it can fit into the Cap notch. Any ideas as to what I can do for this?

And of course, a work in progress. :roll: Any feedback welcomed, as I'm in no hurry to do the mods til I'm sure I've found a viable method to fit that front section. Thanks!
