Phil and Ben, tell me about your A5's. I have a pile of them at home. My favorites being the stright stocked A5s' from pre WW1. Here are 5 early guns 12's and a 16.

Regarding home defense, racking the slide is stupid mach mano stuff. It's a good way to make a good situation bad and a bad situation tragic.
If there is really a chance that your going to need to shoot you should have a shell in the chamber and the only noise will be the safety coming off.
