I have been looking at Rock Island Armory primarily in 9mm. I like the idea of the traditional 45 but since I don't reload I like the economy of 9mm but I have the itch for a 1911 style pistol. I looked at the RIA and they seem like a decent pistol especially for around $400. My questions are...1) Are the 9's just as reliable as the 45's.... 2) Hows the overall accuracy......3) Does anyone have the standard GI model with fixed sights and do you have issues with the lack of adjustible sights.....
