I have a mini .22 revolver somewhere. A HS .22 mag derringer in GOLD.
Plus a .22 short Astra which is really accurate for a tiny .22.
None get carried any more.
The Bauer I had 30 years back is long gone. After pocket carry on a fishing trip I actually needed it. She was bound up with sand and lint. So I used an axe handle to TCOB. Nothing serious though.
I will keep my faith in a J frame now. 158 GR FBI loads.
Recently I opted to carry an LCP since my surgery requires no belt and it is so flat and light it will do for now.
Serious as a heart attack the .25 will still put a hurting on you.
