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).
I have seen people shoot accurately at 100 yards or more with a .38 pistol. However, in general, a pistol bullet can travel, on average, about a mile.
No way to answer- would depend on the pistol.
No. However, .38 Special ammo CAN be safely fired in a .357 Magnum firearm. Both cartridges use a bullet that is .357 in diameter- but the .357 magnum is longer, and more powerful.
The .357 Magnum cartridge is longer and much more powerful than the .38 Special. While .38 Special ammo CAN be safely fired in a .357 Magnum, the reverse is not true. It is dangerous to try this.
Shotgun by far
No more or less 'powerful' than any other pistol firing the .45 ACP cartridge.
The number of rounds a CO2 pistol can shoot depends on the specific model and brand. On average, a standard CO2 pistol can shoot around 40-50 rounds before needing a new CO2 cartridge. However, some high-capacity models can shoot up to 100 rounds or more before needing a cartridge change.
Depends entirely on the pistol. I have a single shot muzzle loading pistol that 2 shots a minute would be good. A fully automatic machine pistol can fire more than 100 rounds per minute. You need to specify WHICH pistol, as there is no one answer.
No more than any other 9mm Parabellum pistol on the market. A gun's only as powerful as the cartridge it fires allows it to be.
Shoot better practice more.
No specific term of reference. There are semi auto pistols that fire rifle cartridges, and are much more powerful than standard pistols.
