If you are talking about a PCP (PreCharged Pneumatic) rifle. With a .45 caliber pellet, then "Yes" It can. I don't believe there is a 40 Caliber pellet gun.
no there is not a gun called a 40 because thereis no 40 caliber gun
If you mean a .40 caliber bullet in a .32 caliber gun- no. The bullet would be 8 thousandths of inch too large to fit in the gun. Caliber refers to the diameter of the bullet, so a .40 caliber bullet is ABOUT .40 inches across, and a .32 bullet ABOUT .32 inches across.
My gun is a .40 S&W. Thanks for asking.
The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
No
The model 19 is a 9mm only proposition. The model 19 is not available in .40 caliber, but the model 23 is the same size gun and it is a .40 caliber gun. Some people would say that the model 23 is the .40 caliber version of the model 19.
Absolutely not.

A Smith and Wesson M&P 40 is a .40 caliber hand gun.
The most common hand-gun caliber used to be 9mm Luger. Recently I bought a pistol and took a self-defense course. Now it seems the most popular caliber is the.40 Caliber Smith and Wesson.********There are popular, and there are most common. The most common gun caliber is .22 rimfire, in terms of the total number sold.
