Nothing wrong with the smaller calibers. There are times when the larger, more powerful calibers are needed, but they will all pretty much do the job with good shot placement. I've always heard the .25acp degraded as a worthless caliber that will just piss off whoever gets shot with it. When I was 9yo, my mother and father were divorced and my 33yo dad had a new girlfriend. After a time, he decided to cut ties with her and she calmly walked over to her purse, pulled out one of those cheap little .25acp pocket pistols and shot him within a 4-6' distance. He fell face down and she stood over him and fired a second shot into his back. Later in life, (about 40 years later), I found the court reporter that recorded all testimony at the Arraignment and the Trial. (believe me, that was a surprise to find her at her age, and that she had held onto all those records for all those years.) The Coroners report was surprising. Both bullets had passed through his heart and out the other side of his body. One, front to back, the other, back to front. One of the bullets was found on the gurney at the hospital, apparently fallen out of his shirt. The Coroner testified that either shot would have been fatal.
Now keep in mind that I would rather carry a .22LR or .22magnum than a .25acp. But all the "bigger is better" hype doesn't mean squat when you know, personally, what any of them "can" do.
