Depends on the Thompson. If you mean the Thompson submachine gun, yes, they were made in caliber .45 ACP (and other calibers as well). However, there are other Thompsons. I have a Thompson Center muzzleloading rifle that is .50 caliber.
The Glock pistol in caliber .45 GAP.
No.
No, you cannot safely shoot a .45 caliber bullet from a .40 caliber handgun. The .40 caliber handgun is designed specifically for .40 S&W ammunition, which has a different casing size and bullet diameter compared to the .45 caliber. Attempting to use .45 caliber ammunition in a .40 caliber firearm could lead to dangerous malfunctions or serious injury. Always use the correct ammunition specified for your handgun.
No, it won't fit. The .45 caliber bullet is 0.45" in diameter; the .30 caliber bullet is .15" smaller. The brass is different size too.
Yes, you can shoot .38 caliber ammunition in a .357 caliber firearm.
45
None. While there are firearms made to shoot .45 Colt AND .410 shotshells, they are designed and made to do that. A regular .410 shotgun is NOT made to do that safely.
Can I shoot 380acp caliber out of my 32 pistol?
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.
Yes, you can shoot .38 caliber ammunition in a .357 revolver because the .357 revolver is designed to also shoot .38 caliber ammunition.
