My "old" 220 is a better shooter than my newer Sig's. Heck its a better shooting/more accurate gun than all my other pistols except for my two Wilsons. Pretty guns don't always make the best shooters... I think they can be converted back to DA/SA...
I love my sig's (I have several). I'm in ATL and have a sight tool when you get ready to swap them out. I usually order my sights from Top Gun Supply. I like the Meprolites night sights.
Great gun!
