AHA! Found that screw, I tried rippin' it off before but this should make the process a little easier
EDIT/
This was harder than previously thought...for some reason the screw was "damaged" or rusted or something...anyway the screwdriver wouldn't grip...So, I took a drill, and drilled off the top of the screw, then taking a flathead screwdriver I pried the sightrail off of the gun and slid it forward, then taking a vicegrip, i grabbed the exposed screw body and pulled it off. After moving my quick strip pin thing in a little the sightrail slid off leaving a better looking, lighter, and smaller profiled gun. I'd post a pic if I had a digital camera, if you really want one I'll borrow my friends...thanks for the help
