Yeah, I kept looking on Youtube and the like and I eventually found a set of good
disassembly vids, although the presenter is a complete douchehat. So my loading nozzle springs are wonky at each end, and I think I'll have to sand the BBU to get it sit/cycle properly. It's a shame, too, because I always disliked glocks before this, but I find the ergonomics and design to be a real dream. Everything's close to my firing hand, it's light, no corners or bits to snag on gear..... ah well, at least I have a good project gun.
