My advice is to get one, you will love it.

The Moon Clips are easy to load by hand, and there are aftermarket loaders that work as well. I have one buried in the safe, but never use it.

The 45 Colt can use Speed Loaders because it is a rimmed cartridge, and does not use Moon Clips.

Moon Clips can be used for rimless cartridges like the 45 acp, 45 Super, 460 Rowland, and the 45 Win Mag. All of which will work in the 45 Redhawk.
