I was bored out of mind last night, while the wife was watching Glee, so I figured I'd go on an adventure and detail strip and clean my 27. First of all, I can believe how simple this gun is to strip down to bare bones. Secondly, I can't believe how much crud I had built up in the slide components and the frame. So after about an hour all the crud was gone the gun was lubed and reassembled, and I was a happy camper. I've been shooting the 27 regularly for about 8 months now and never realized how much crud could build up over that time. After reading the thread on how often people detail strip their glocks I figured I wouldn't find to much dirt in there, but there was a significant amount and I'm glad it's gone now. Just my experience.
