FYI, Just saw this and thought it was pretty good. Diamondback Firearms has put out a firearms safety course online that is free to the public. The site is http://diamondback.oursafehome.net/.
I went through it. Pretty good info and got some coupons for discounts on some holster websites at the end. All in all I think it was worth the 45 min it took to go through it.
