Have you thought about a Sig P226, P228 or P229?
Actually the first pistol I ever fired was a Sig226 and, well, there's just nothin like that first time ya know I would love to have a sig but they are bloody expensive, even used. Everytime I think about picking one up I talk myself out of it.
If the RIA is that good I may just have to pick one of those up...dang, another option into the fray!
