I'll make another set and as I've said above... If there's an interest, I could make more but I'm not trying to start a business here.
I've only done it to replace the grips that were no longer any good or not long from being any good on my own gat. I'm happy to make them for people, I would have thought £15-£20 ( upper end to include fees and p&p ) should cover it in time and materials...
In answer to the question above and to confirm, Demon and Creed grips are the same. The screw spacing, profile and screen window placement are all identical.
I used my rubber grips (before they gave up) to mark out the template and used my Dremel-ish tool to cut out and finish the shape off, then wet and dry paper to the edges and a good wash over with soapy water and a dry with a microfibre. I even treated the inside of the grips with cat-crap so there'll be no fogging
