Any RIA owners in here?

I bought my first Rock Island .45 last week. It is the Govt. Model Tactical that has the beavertail grip safety, target hammer and trigger and Novak style sights. Its a pretty good shooter, Ive only put about 100 rounds through it so far, but no problems yet. The factory grips were the only complaints I had, but after putting a set of Pachmayrs (sp?) on it, it looks pretty sharp.

I bought one from a dealer in KS. he advertized it as a rock river but when I got there it was a RIA. I have to clean it every time I shoot it or the slide doesen't go all the way forward.it rubs against the frame.
