I am not that familiar with the history of the single action versions of the P226, and I was wondering if someone could give me a short synopsis.

I own a second-hand "P226 Elite" SAO. This seems to be a forerunner to the "Legion" series, but other than stocks and finishes, what other things distinguish the later Legion pistols from the "Elite" variant.

Thanks in advance.

Far as I know the trigger guard undercut, the beavertail size/shape, sights, grips, and trigger. There may be other things.
