...in a holster is the way I prefer to carry pistols and revolvers. I wrote about just that and my criterion to select a holster here. I wrote about those topics because the way you carry your pistol or revolver is important, it could mean the difference between whether or not you are the winner in a life threatening situation, whether or not you are able to retain your sidearm, whether or not you shoot yourself with your own gun. If anyone doubted me when i said that I thought a bag of just about any sort was a poor choice in which to carry a handgun, maybe when you read this: S.C. Student Shot by Own Gun in Book Bag Pleads Guilty my point of view will seem to be a little stronger. Sure the bag this pistol was carried in probably was not made for carry. Sure some handbags are made with internal holsters or carry pouches. I still contend that any bag which you pick up and put down is a bad choice for carry. I also contend that there is much more of a chance of a foreign object getting into the trigger guard and against the trigger when carried in a bag - whether or not that bag has an internal carry pouch or holster - than when you carry in a quality made hip holster. Your choice, just like it was this kid's choice. On this topic, learn from his mistakes and not from your own. That way you will, in my opinion, stay healthier.
All the best,
