Blackhawk thumbreak for 1911's. It is right handed and has an open bottom so it will fit any single stack 1911. I carried my Commander in it, and the front sight just barely poked out the bottom. Only reason I'm selling it becuase I bought it while I waited for my Milt Sparks VMII, and the VMII showed up early. - $35 shipped ConUS OR trade for a couple Glock 36 mags!
