How about some little pocket auto's. Three little .25 Semi automatics.
There is a Bretta, FN Browning's Patent and a Colt, Junior Colt
The Colt belonged to my dad. I can remember back in the 60's he was a manager of a Pangles Grocery store. There was a rash of robberies. He went out and got this little .25 and would wear it on his belt open carry in the store.
I really don't know what he would have done if he would have had to use it.
The FN belonged to my great aunt. She lived in an apartment in Lima years ago. She was going to her car one afternoon. A guy stopped her to rob her. She was a feisty ole gal for that matter she still is at 94 years old.
Still lives on her own but can't have the gun in her apartment. Any way she had the auto in her hand which was in her purse. She said you better get away or I will shoot you with this gun. The guy took off! I think it was a good thing for both of them.
