how hard is it, technically? My Omer Cayman was stolen from my truck a few days ago. That gun practically lived in the truck, and I have a silly habit of never locking it. My best gun, but it is apparently out of production and 75cm is not available anymore. I wonder, if I buy 95cm one and cut the barrel? Seems like it should be doable, but I have never done it before. Anything I should know?
