Ibero, I got my rails at Houts Enterprises => http://www.houtsenterprises.com/cx4.html My top rail was about $50 (with shipping). Definitely a smooth shooting little gun. I think it's the perfect home defense weapon. Small enough to easily carry at the ready through a house, but the longer barrel makes it more accurate, and you can use it at medium distances too (like 100 yards) if your in an urban area, and have some kind of situation that calls for long range protection of your property (Katrina?). I've got a folding front grip, a light, and sling on mine. I got a red dot scope too, but didn't really like it. I prefer the iron sites. That's how I learned to shoot, and like it better. The CX4 is also extremely easy to break down and clean. I really like mine.
