The most powerful air pistol would be a Air Force Talon-p 25 Caliber. This is a PCP class air pistol. The air tank uses 3000 PSI to fire the pistol.
A powerful pistol will have a powerful recoil.
The pistol in the movie Dirty Harry was a .44 mag - "the most powerful handgun in the world" according to "dirty" Harry Callahan.
First, it is rifle, not riffle. Second, no, or we would shoot tanks with a rifle. Cannon are more powerful. Finally, depends on the rifle. I have a .22 rifle and a .44 magnum pistol. The pistol is far more powerful than the rifle. I also have a .22 pistol, and a 30-06 rifle. The rifle is far more powerful than the pistol (in THAT example).
No way to answer- would depend on the pistol.
Most likely it would be the Evanix Hunting Master AR6 by Evanix. It fires a 22 caliber pellet at 1000 FPS. This pistol is in a class of PCP pistols. (Pre Charged Pneumatics.)
It is the same power as any other firearm that is firing the same caliber cartridge. Contrary to myth, this is NOT the most powerful handgun in the world- not even close.
No specific term of reference. There are semi auto pistols that fire rifle cartridges, and are much more powerful than standard pistols.
Beretta Elite 2 has more power
Considering PISTOLS ONLY, NOT rifles then: The Beeman P-1 is amongst one of the most powerful. But there are most likely others. But that is only in .177 caliber. Real power is in the PCP (PreCharged Pneumatic) air guns like the .25 Cal TalonP or the .22 caliber Marauder pistol. see the link below
It was a Smith and Wesson 44 Magnum "The most powerful handgun in the world" according to Harry.
Electric pistols are not powerful. If you want power, I would recommend a green gas pistol.
