Now that we got the slide off the receiver, we'll work on the slide first and be getting to the receiver later.

Pull the recoil spring out towards the rear.

Make sure barrel link is flat against the barrel and remove it out the front of the slide.

At this point we have taken down the weapon to whats called "Field Stripped". If you just needed to do a quick clean, replace the barrel, or recoil spring/guide rod this is all you need. For deep cleaning after shooting we'll keep going.
