A friend has a 226 Legion, so naturally we compared the two. We both liked the Arex controls better. I've put a few hundred rounds through it. No issues. Sorry, no target pics, but it shoot nice groups.
I bought some tritium sights for it, but I'm not sure I'll use them. They are tiny, just like the Legion.
Any more questions, just ask!
Edited to add: The one thing I don't care for is the anodized green frame. It's too metallic looking. I'd go all black if doing again.
