The Browning is 4 inches long. The P32 is about 10% smaller than the LCP.
The .25 auto is a pretty effective little pistol cartridge-regardless of Internet naysayers. No pistol caliber is a death ray-they all need a CNS hit for a definite stop-even a .45.
Now, someone will post .22 lr ballistics from a rifle barrel, and ballistics for the .25 from a 2" barrel-and tell us how much more powerful the .22 is.
