Always thought of Elmer (I love auto correct) Keith as somewhat of a cowboy. Remember him writing about his younger days in Montana, being taught about using six-guns from a Civil War veteran, running wild horses, herding sheep and having a cow ranch in Oregon. To me, that sounded pretty cowboy.
As far the Threepersons and Lawrence 120 Keith, agree they don’t cover much of the gun and found without the strap either didn’t hold a gun very well, at least the ones I had experience with. Always considered them a fast draw holster. Preferred a deeper holster that covered the trigger, rear sight, protected the hammer somewhat and had some type of strap or hold down when I was hunting. I have never actually been in a situation requiring the ‘emergency’ use of a handgun, whether in bear county out West or in Alaska, but I was confident even if hanging upside down from my boots my six shooter would be in my holster until I needed it.
One experience about holsters without straps or tie downs that always make me laugh a bit, is a story from a group at a club I belong to that went to shooting event. One gentleman had removed his gun belt and was in the process of hanging it up when his original 1851 took a dive from it’s holster into the port-a-potty he was about to use. He managed to fish the gun out (said he would have left if not an original) but not without quite the audience cheering him on. He left the event early.
