RTFM?
I have been shooting since I was a little kid, I still look over the manual when I buy a new gun. They don't print those things up just because they have a bunch of extra ink and paper sitting around. Unless you have been using and reading about that PARTICULAR firearm for years it is likely you can learn something by reading the manual...if only the field strip procedure.
What happened to create a world where people shoot themselves because they are too stupid to seek help when dealing with an unknown device that they know is dangerous? All they had to do is pick up the booklet and read.
There was probably even a sheet of paper on top or a sticker that says "READ MANUAL FIRST".
