a colt firing a 357 magnum cartridge results in the jamming and possibly explosion of the firearm
No. If it will even fit (the rim of a 44 magnum cartridge is much larger than a 45 Colt) it would be very dangerous to do. 45 Colt firearms were not designed for the forces of a 44 Magnum cartridge.
Although it can be done, DO NOT !! Never fire ammunition in a weapon that it is not chambered for.
No. A .357 Magnum revolver (not an automatic, lever action, or anything else with a headspaced chamber) can fire .38 S&W Special ammo, but not .38 Long Colt.
No. .38 Long Colt was the forerunner to .38 Special- and was originally a black powder cartridge. The .38 Special is more powerful- the .357 magnum is MUCH more powerful. Neither the Special nor the magnum should be fired in a gun chambered for .38 Long Colt. This is VERY dangerous.
just the cylinder change
There are numerous handguns that will fire more than one caliber or type of ammo. The Taurus Judge will fire .410 shotgun ammo or .45 Colt ammo. Smith and Wesson has just started producing a gun similar revolver called the Governer that will fire .410, .45 Colt, or .45 ACP. You can fire .38 special in any gun that is chambered in .357 magnum (but not vice-versa) or .44 special in a gun chambered for .44 magnum (but not vice-versa). Also there are other types. There is a very rare revolver called the Medusa that will fire anything in the .38 or 9mm family, including 9mm Kurz (380), 9x19mm, 38 special, and .357 magnum.
There are a dozen different cartridges with 38 in their name, and SOME are compatible with the .357 Magnum. A .357 will fire .38 Special, .38 Short Colt, .38 Long Colt- but NOT .38 S&W.
This is the ammunition the gun is designed to fire, it is not hard on the gun.
Ordinary .410 shotguns CANNOT safely fire .45 Colt, .44 Magnum or any other cartridge. Stick to .410s. They are designed for a lower pressure, smaller projectile. No. Bad ju-ju. Don't.
