Hi-- With regard to my new Glock 20 S/F and my Glock 29, when disassembling the guns, when I pull the slide off of the receiver I note that the back end of the recoil spring assembly comes up and out of its seating notch on the barrel lug. It doesn't fall out of the slide but re-indexes higher up on the lug. Is this normal? Any thoughts. Thanks, Semper Fi.

It's completely normal... As the gun gets some rounds through it, the spring will loosen up a bit and the parts will mate. My G17L drove me nuts with the same concern for a while... In fact all my long barreled Glocks started out like that.
Completely normal. The seat notch on the barrel is just for the re-assembly process. When the slide racks on the body, the spring actually reseats to it's correct position within the body itself... which is slightly lower than the barrel notch seating location.
Yes. Absolutely normal. Here is a quick explanation:
When the gun releases a shot, and the Slide moves aft, so does the Barrel, as it is locked to the Slide via the Barrel Hood in the ejection port. After about 1/8-1/4", the Barrel Lug contacts the Locking Block [ramp] which drives the aft end of the Barrel (chamber) downward, unlocking the Barrel from the Slide. When this happens, obviously, the RSA (Recoil Spring Assembly) is also forced downward.
As the Slide cycles back forward, it contacts the Barrel and forces it back forward as well. As the Slide and Barrel move forward, the Barrel Lug slides back up the Locking Block [ramp] and locks the Barrel back to the slide via the Barrel Hood in the Ejection Port. During this process, the RSA moves back upward with the chamber end of the barrel, but not all the way back into the crescent cut out. There is a small amount of slip.
Completely normal. Welcome to the Forum, and enjoy your Glock!
