IMHO, the advantages of 9mm Luger in a revolver, namely cheap ammo, are outweighed by the extra trouble involving the need for a clip or the extra mechanism for extraction without it. If you want a revolver, my suggestion is to go with a .38 Special/.357 Magnum and forget 9mm.
Not a subject I pretend to be very knowledgeable about, but isn't one of the advantages of the clips is the ability to reload faster. I never considered it a negative. But then I have no experience with using them either.
