I have a Beretta 950 in .25acp. I carry Hornady or Winchester defense ammo. That's right there is defense ammo for the .25acp, and it works. I have shot a large number of Nutria with .22lr hp and .25acp defense loads. The critters shot with the .22 required several shots. The ones shot with the .25 were all one shot kills. No, it ain't a large caliber pistol, but will do the job. Of course the .25acp would not be my first choice for defense, but I ain't sceered to carry one. Believe what you want, 'cause you will any way.
