For the money I think a CK Arms SS is the best thing going. You could also get a Springfield TRP or STI Trojan and send it in for a trigger job and aftec extractor and be pretty good. Depends on what you want to spend.
I have had great experience with 1.180s I am thinking about going to 1.200 just to see if there is a difference. Also don't want to reinvent the wheel.
Both are great! Get whichever one you like the the looks of best. Only thing if is for a single stack gett the Boss. The springer sits a little to low to be legal.
