All I can share is based on my real life experiences.
We did not have the other offerings back in my day. I am from the deep south and know all too well about the heat and humidity, including Houston and nearby areas.
Yep, me and mine carried .25 ACP Beretta Jetfires, and Beretta 21 A's chambered for .25 ACP ( and .22 lr) along with other offerings...
I and mine were in high risk, serious work. While I respect the late Col. Jeff Cooper, I and mine have "been there, and done that".
I ain't gotta problem today carrying a .25 ACP or .22 lr either...
Time passes and "some I folks run with" did do some testing and evaluation of the newer offerings mentioned.
For a fact, one, based on his experiences when still active in Special Forces, still has "reasons" for the .32 ACP. [His experiences like others whom have btdt are the reasons I too like .32 ACP]. It has to do with what is "normal", allows one to "blend in" and legal/political reasons.
[Keep in mind, some countries do not allow the private sector to have what police/military use].
Understand, I and mine, for what we did, often had to be "discreet". This was before NPE's and other stuff came to be. This includes Internet forums and Internet Kiddies, posting stuff about things they have, and will never have real world experiences with.
The gist was/is...when some folks did some testing and evaluation, with some guns, including the ones in original post and I was involved...
The .25 ACP ( and .22 lr) still have a viable place in today's world. The Jetfire is "that" damn reliable and accurate, and affords deep concealment. So does the 21 A in both caliber offerings.
I am not that old at age 56, just I started too damn young in some serious stuff. While I have IT education from college, my real deal world experiences are greater.
All I can share...
But one would be very very wise to have mindset and skill sets before tool sets. I don't care if the "tool set" is a .44 mag, 45 ACP. .38 spl or anything else, including a "mouse gun"
I am the only one left alive of a work I was born into and did for decades...
My two cents, for what it is worth.
