RIA has a much better warranty... Their pistols are guaranteed for life. Even if you are the 30th + owner. And their customer service is gold line.
You may find a sub $350 to $400 gently used RIA Tactical model out there.
This.....If you get one that doesn't work, you send it in and they will work their magic. I'm not saying this as a "go buy a crappy pistol, they will make it better the second time" but I am saying that complainers are louder than happy customers. My RIA's have all run fine out of the box, but if you are worried about getting one that isn't perfect they will take care of you.
