The most comfortable IWB rig I`ve ever used is my kydex Kytac Braveheart. It`s very secure, comfortable and fast. It also keeps sweat off the gun in hot weather. I`m able to easily conceal a P-97 under an untucked T shirt with it which I`ve never quite been able to do with any other holster. Check out
www.kytac.com ,they make holsters for your Commander. Dave at Kytac is great to deal with and the service was very fast. Marcus
