No. The .38 S&W is a different cartridge from the .38 Special. Basically, the .38 S&W is shorter, fatter, and has less energy. It will not chamber in a gun meant for .38 Special.
No such caliber as .32 Special. Use the caliber of ammo marked on the gun.
38 special.
Yes- but not very common. There is an automatic pistol caliber known as the .38 Super, which does not interchange with the .38 Special revolver cartridge. There have been a small number of target pistols built to shoot .38 Special Wadcutter target ammo. And there is at least one auto pistol made in caliber .357 Magnum (revolver cartridge). However, revolver ammo is rimmed, and auto pistol ammo is rimless- there are usually feeding problems when an auto pistol is made for revolver ammo.
A ".38 +P revolver" is simply a .38 Special revolver which is rated to fire +P loads. It's still a .38 Special, and the +P doesn't change the dimensions of the round itself.
NO, NO, NO, NO, NO, NO, NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DO NOT EVEN TRY TO DO THIS!!!!!!!!!!!!!!
38 Special. Stay away from +P
Depends on how old the revolver is.
Yes, you can shoot 38 specials through a .357 magnum revolver.
38 caliber revolver ammo

Can I shoot 380acp caliber out of my 32 pistol?
