There's more holsters available for the 1911 than any other gun on the market. I went through the gambet of trying several types. I setteled on an Alessi thumb break, high ride, belt mounted, hip holster. There are several other brands with the same basic style including Safari, Dillon, and Hume..
Here's my criteria: I must be able to draw the gun from most any position. The holster should not limit walking, sitting, driving and even laying down. The holster must have a thumb break strap that interrupts the cocked hammer. The holster must completely cover the trigger and not interfere with the thumb safety.
