Got my first Glock today (G19) and I cant wait to take it to the range tomorrow before work. I've never fired one before but it feels great in my hand so hopefully I'll be able to hit paper with it. Anyway, bear with me here...I went and stripped it down into its five major parts and gave it an initial cleaning and lube. Nothing to it. Anyway, it seems to me that the recoil spring just sort of 'rests' against the barrel lug ponderously, and is not actually held in place by anything except the spring tension. I put it all back together and the gun seems to cock and function correctly, so I think I did it right(?) Like I said, haven't had a chance to fire it yet so I wanted to make sure I didn't miss anything, lose any parts, etc.
