I have a problem, too many holsters too many guns. All of my holsters are belt pancakes, and I am constantly pulling my shirt to re-coverup my "print" when I bend over to look at something.I want to buy a shoulder rig and want to know if there is a company that sells a rig that I can change out the gun holster to use the rig with different guns. I prefer to use a nylon rig. I carry a 3 1/2" Springfield Armory XD-40, sometimes a Colt 1911 defender 3 1/2", and I just bought a Beretta 90-two in .40. Any help would be great. Thanks. Ryan
