Tucker's Gun Leather makes a phenomenal holster IMHO. I use their "Cover Up" IWB with a 5" 1911 and it is perfect, adjustable for forward cant, how low it rides in the pants, and tension on the gun. Only issue is my front sight snags occasionally but I'm about to buy some Wilson Night Eyes when funds allow.
