LOL, I was just looking for a good pic of the M-240b (I want one!) and found this instead. One of the reasons I hated being in the Army was that firearm safety was a joke.
I'm not a big handgun expert, so I don't know if other automatics are the same way. I found it disturbing in a way to know that the weapon was that easily disabled. We had another SGT who could do the same thing but actually was pretty good at taking the slide off the top of the weapon as well. He could do this in like one second and leave you holding only half your weapon- it was a funny trick but I didn't think I'd have tried that one. Personally, I'd want a handgun that fired even if it was totally jammed into someone's belly (like they were laying on top of me with all their weight). I've never figured out why they can't just make a revolver type handgun with a larger cylinder or maybe with two cylinders so that you could quickly swivel a full one up into place when the top one was empty- that'd give you ten to twelve shots with a low malfunction risk. I'm no expert or nothing- I'm sure one of you handgun nuts will tell me it's a hokey idea ;-)
