IMHO, you can not go wrong with a RIA. I have three (selling one of them if you are interested) and I love them!! I actually sold my Springfield to get another one (kind of funny sold RIA, bought Springfield, sold Springfield and now have another RIA) cause I love em. I have owned Les Bauer (sp?), Springfield, Colt, Norinco, Kimber, Taraus, and RIA. Except for the Kimber, I would recommend the RIA over them all, but that is IMHO. Wilson combat drop in stuff works great (no gunsmithing) and the only thing I have heard recommended is to replace all springs first.
