I am the proud owner of a new Smith 460 and have a question that does not seem to be addressed in the manual... The gun comes with two interchangeable compensators, and specifies one for use with lead bullets and the other for jacketed bullets. Although I can see the porting is different, my question is, why the difference?????(and would it be dangerous to confuse the two?) I don't mean to sound paranoid, and am a longtime M29 owner, but I am approaching this beast with caution!!!
