RE: .25 acp...

I was responding to a recommendation for .22LR as possibly a better choice due to better ammo choices... which is humorous in today's world in its own right, .22LR at a reasonable price being rarer than hen's teeth.
Those hen's teeth can be found on store shelves, nowadays, and you don't have to mortgage your house to buy a brick. (I've been on vacation this week and have noticed signs in gun shop windows saying, "ammo - no limits.")
We agree, at least, on the likely
ineffectiveness of the .22 round when used in a short-barreled pistol. Unless that round is shot out of a longer barrel, it doesn't perform particularly well. The same is true of the more-powerful .22 Magnum -- which is not impressive when shot from the shortest barrels. More importantly, most of us who have shot a lot of .22 over the years have probably had FAR MORE ignition failures with .22 than in all other rounds, combined. THAT alone would dissuade me from using it for self defense...
You said you've seen references to .32 acp, .380, and 9x18 rifles -- if so, you've used your reference books or search engines far more effectively than I have. I've only seen .32 acp used in a special class of rifle-like weapons (sub-guns and auto-pistols, which are really a different category of weapon), and I've never encountered a .380 or 9x18 rifle. (A sub-gun in 9x18 wouldn't surprise me, but I've never run into that beast, either.) I did find a reference to a .25 acp rifle, but it was a one-of-a-kind project gun.
I personally can't understand why anyone would want a .25 acp weapon when there are so many other options in terms of weapons and commercially-available ammo in slightly larger calibers. And, some of the smallest .32 and .380 guns are not much larger than the .25 pistols.
I know a .25 acp pistol is better than a pointed stick, but...
