I've been shooting awhile, but my wife is new to handguns. She currently owns a .380. Because of the price of ammo, one of our friends told us that she should be practicing with a .22 handgun. The purpose he states is: 1) price per round and 2) muscle memory. I can see some logic to this but I am just not sure. Practicing with the handgun she will use to defend herself seems to make more sense to me - getting used to the weight, feel and kick after each shot. I have taught her how to squeeze the trigger through "dry fire" so this idea seems to have some merit. Is a .22 the best to train and target practice with? I would appreciate your advice. Thanks
