I never OC and certainly wouldn't OC without some form of positive retention. I have 2 holsters I use for my Commanders. A Galco suede 'paddle' with thumb-break , and a Fobus without any positive retention. The Fobus rattled a bit so I took a heat gun , heated it up , squeezed it a bit and let cool. Much better. I have about 5-6 Fobus holsters for several guns. Cheap and durable.
