Why do folks like the .25 and .32 for self defense use? They are so anemic for that purpose and there are so many other better choices available in more potent calibers??? Just don't get it! Don't get me wrong, I am not volunteering to stand in front of you guys that like em and let you shoot at me!!!
Says who?
Honestly, the only folks I've ever seen calling .32 ACP anemic are those who erroneously site the proliferation/popularity of .380 ACP pocket pistols as evidence of such or otherwise make lame strawman arguments like "the police don't use 'em" as if that means anything.
Factually speaking, the .32 ACP was considered a respectable self-defense cartridge prior to the release of modern lightweight locking breach micro .380s, and had seen use in both the Military and Law Enforcement for decades in Europe.
The reason why you don't see .32 ACP pistols anymore is because it is now possible to get ultra lightweight/compact pistols in .380 ACP, ergo the average person (most of whom know little/nothing about firearms) opts for the more powerful option of equal size/weight. It has nothing to do with the .32 ACP being anemic but rather that it's possible to get more power out of pistols of similar size/weight in .380 ACP without having to sacrifice all that much in terms of ammo capacity nor stability. (Especially in modern locking breach .380 pistols.)
Heck, there is a large amount of folks who consider the .380 ACP anemic and argue that folks are better off carrying a slightly larger/heavier gun in 9mm Luger.
Meanwhile, true experts have been saying for decades that shot placement is more important than caliber, that shootability is more important than energy, and that the fabled hydrostatic shock simply isn't even possible in handgun velocities, yet folks continue to ignore that, placing some arbitrary limit on which cartridges are effective, and sadly more often than not choose to associate the cartridge they carry with their own masculinity, even when it comes to mouse guns.
Personally, I carry .380 ACP in my EDC rotation, but if there were a practical reason to choose .32 ACP over .380 ACP, then I would consider opting for it if I felt the benefits were worth the trade. At this point in time though, .380 ACP has effectively supplanted .32 ACP in modern lightweight carry pistols, albeit not strictly because .32 ACP is weak nor ineffective, merely because .380 ACP is arguably more effective.
