I will admit, however, that I don't have any extended safeties, or ambidextrous safeties, on my two Commanders. If the original safety is "firm" (for lack of a better word) and is worn on the inside, as would be done for R hand carry, it is very difficult to brush it off accidentally. I'm not against the concept of extended safeties, but I don't have any experience with them. If I was L handed, I think I'd get an ambi safety and have a gunsmith do something to the normal safety to minimize it. Maybe trim it to look like a GI safety, so it wouldn't get snagged.
