When I take the slide off the recoil rod/Spring is very loose and often just falls off. When its on and in the gun it sits fine and the gun fires properly. I shot 30 rounds flawlessly so far. Its a 21SF RTF2. Is that normal? It will sit in the higher seated area of the barrel but when it clicks onto the frame it lowers to the lower one and that's why it becomes loose. Is the spring just a tad bit too short? I do not have a camera to post pics. Also are blue label Glocks lubricated better at the factory? This Glock was extremely well lubricated. It had the copper grease all the way down both rails and I couldn't even wipe it all out when cleaning it. On my new 26 and 22 that I had it came out very easily and was no where near as well lubricated from the factory.
