The 32 is a slayer of men...how many thousands and thousands have died in trench fighting/street fighting between WW1 &WW2. Both wars saw extensive use of 6.35, 7.65, and 9mm handguns.
The 81 is going to be a good choice for a lot of people. I would advise carrying FMJ or maybe a JHP in the pipe and one on top of the magazine. The "super high tech advancements in bullet technology" that is used to finally develop 380 loads that expand AND penetrate deep enough...the SAME can be applied to 32...and should be...most JHP are old-school designs and too heavy to expand and get enough velocity to keep punching. Its a balance, HP weight to velocity ratio giving enough expansion/penetration given barrel length. I prefer FMJ, but want to try reloading some HOT 60gr loads.
32 SHOULD be a preppers best friend...reloadable 22LR alternative. Sure 25ACP would work, and be technically more cost effective given materials...those bullets are TINY. I'll try it one day, but I couldn't imagine doing thousands... 32 is big enough to be reasonable. Load up some SD ammo, then load up mouse farts for small game. I am working on finding ways to incorporate it into my preps as such. Reloading is the LONG game.
Plus a 32ACP can be loaded HOT in these Berettas. I heard some 25ACP loads of a 50gr bullet going almost 1100fps...Beretta 950 test gun. Survived it. Those are excessive, but we ALL know 25/32 ACP is watered down. Point I bring up is, Beretta builds TANKS of a gun. The 34/35 and 81/84 should be able to handle any hot load short of dangerous. Not sure how a VZ61 would....but I would imagine it'd be fine.
Tldr; 32 ACP is underrated and not supported as well as it could be. It's often watered down like 25ACP and more. Real investment in tech, could boost its popularity. Offering higher round counts/recoil ratio to 380 handguns.
