I would use speedloaders with my SP101 in 9mm if Federal would bring back the 9mm rimmed (c1989) as the pocket carry of moon clips can be a challenge. For now I will use the moon clips, I like moon clips because of the sure ejection of empty brass, I also like speedloaders (Comp3 or Comp2's) and with practice can reload just as fast as a moon clip or a semi auto pistol. So my answer is speedloader if ammo is available for it.
9mm Federal Rimmed Cartridge History: The 9mm Federal rimmed cartridge was introduced in 1989 for the Charter Arms Pit Bull revolver pistol.
The 9mm Federal is a rimmed version of the 9mm Luger. Not long after the introduction of the pistol and ammunition, Charter Arms went out of business, and as no other manufacturer produced the revolver pistol, Federal Cartridge Company soon stopped producing the cartridge, making it an obsolete item. You can "NOT" use moon-clips in this revolver to fire regular 9mm Luger rimless cartridges. This cartridge has been obsolete for over 25 years.
