I was shooting a steel match last summer with a fella that had a stroke several years back and lost 90% usage of his right arm and he was right handed. He mounted the slide pull on the right side of the slide, like guns in open class use, and he keeps a nylon necklace with a 1" diameter round ring around his neck. He puts the gun on the table, slides in the mag, taps the mag on the table, and uses the necklace with the ring to rack the slide, de-cocks, holsters and is ready. Every action has the barrel pointing down range.
He said "a little stroke was note going to keep me away from the range". I was very impressed!
