Thanks for reaching out Mark! It's a yes and no type of answer. Your Charter Arms revolver is in fact rated to safely fire 38 Special +P ammunition. Ovepressure ammo will accelerate wear and tear on the cylinder and barrel, but limited training and potential self-defense applications will not destroy your revolver. But because a snubnosed revolver's barrel is too short for an overpressure round's extra powder to fully combust, a +P load will succeed in generating added recoil without actually imparting significantly more velocity and resultant energy to the bullet. In other words, +P will give your revolver a stronger kick (and more muzzle rise which complicates accurate rapid fire) without the accompanying benefit of greater stopping power. But this view is not universally shared – plenty of people say that +P in a snubnose is still worthwhile. Whether you should prefer +P ultimately boils down to your personal preference, but be advised that it may only handicap you during a personal protection scenario.
