I have a Blackhawk paddle type holster for my .45 ACP. It was highly recommended by three different guys at the Cabelas where I purchased it. All three had been over in the sandbox and had used these style holsters where and when it counted. The model I have locks the pistol solidly into the holster and cannot release it without the trigger finger laying down into a groove on the outside of the holster where it depresses the release. Unless it is the wearer's gun hand, it is almost impossible to release the mechanism and free the gun.
Second benefit is that the trigger finger is automatically "indexed" properly OUTSIDE the trigger guard and laid along the rail in a safe position when the gun is slid out from the holster. The paddle portion of the holster slides over the belt and waistband of your britches. That leaves the gun holstered outside the pants. There is a tiny little bit of plastic that grabs a hold of the waistband of your britches that makes it damn near impossible to remove the holster short of dropping trou' and using both hands. 'Nother benefit if someone tries to pull the whole gun and holster away from you. Just don't wear Chippendale style tear-away pants with this holster. Don't ask me how I know this.
With the design of the holster, the trigger is covered by the holster, so it is pretty damn safe to carry the 1911 in the old "cocked and locked" position, even if I can't make myself do that. But that feature is also pretty handy for a double action pistol, keeps you from pulling the trigger while trying to pull the gun, one of the most common unintentional discharges*.
Hope that helps.
*There are no gun accidents, only unintentional discharges. Guns don't have accidents, someone or something
makes them go off.
