I just think the DA/SA setup is totally unnecessary--it solves no problem that I have, plus I now find Sigs to be all cluttered up with buttons and levers and stuff.
That's funny, I believe the exact opposite. I think SAO is totally unnecessary in light of a good quality DA/SA system. With a good DA/SA I can have a SAO when I want it or DA/SA. In other words, I can choose to use the safety like I would on a SAO or I can choose to carry with hammer down, no safety and a double-action first shot. My EAA Stock 10mm is DA/SA. It has the best Single Action trigger of any DA/SA that I've encountered to date. I like it so much that I'm considering getting one in 9mm (if Tanfoglio makes one).
