Interesting to hear that someone had an issue with that.
I actually found it rather simple in comparison to some.
The first thing I did when I brought mine home was I opened the case, checked the chamber, and tore it down. I have got to see what makes it tick before I ever use it - and I like to know everything I can about it before use. This way, you don't go and do something that makes you look like a fool!
IMO it's one of the easiest guns to field strip and reassemble. I always quickly run the slide back and forth 3 times pull the trigger and bring the slide back until the barrel drops, pull down the slide release and done.
