I sent my G-36 to http://coldborecustom.com for a grip reduction and carry texture. I chose him because the price was right and the pics on his site were exactly what I was looking for. Most anyone can remove the hump on the back strap, the trick is making it look good when your done. My biggest concerns was the lines being clean and the texture consistent. Well Mr. Owens (owner/operator) delivered BIG TIME. Turn around time was great, he had my frame three days. On the third day it was on its way back to me. If Glock had a custom shop that offered this service, this would be the quality of workmanship I would expect from them.
