Great start! We should make this a sticky and include itas " A must read and practice" thing to attend functions and to just be responsible at all times.
Also we could encourage folks to input their experiences and practices for their make of gun so we get a log of all types that might have either past or currentsafety issues or certain things to do to make safe during loading/unloading & handling.
I'll input that my S&W M&P 40c has no safeties at all except the trigger safety. My practice is to always pay attention to my trigger finger (and others)that it is not in the trigger guard and will not accidentally get in there when unloading (racking the slide motion). It's a stiff finger out of contact with gun type of thing that I do conciously. Then I look to make sure it is empty, more than once.
I do dry fire after ensuring unloaded, when unloading when I do take-down for cleaning and when I reassemble it.
As I stated in the thread that got this one going, if you don't feel comfortable carrying a loaded (one in pipe) gun you shouldn't be carrying (IMO). Learn to be comfortable with it loaded by taking training coarses and practice.
