It's wonderful to be a revolver shooter in the 21st. century, as there is such a plethora of speedloaders and moonclips available that, it is possible to have just as many of them as jam-a-matic owners have "clips." (Har har har

)
Anyway, all joking aside there are more choices now than there was just two or three years ago.
Let's start with speedstrips, which aren't speedloaders but are great for concealed carry because they can lay flat in your pocket, but will be much slower than a speedloader reload.
- A new company, Tuff Products makes them for just about all revolver calibers, some rifle and even shotgun gauges, and even in different lengths for different quantities of ammuntion.QuickStrips™ :: Tuff Products
Now, for speedloaders- my favorite subject.

Speedloaders now come in many various pieces for nearly ever single revolver out there- which hasn't been the case until now.
- HKS is the old standby, and makes good quality inexpensive loaders for most makes of revolvers from .22 to .45. They have a good chart that will give you the number of the gun they will fit. Also, they are made of lightweight plastic and aluminum and will not drop the ammunition until the knob is rotated. The disadvantage is that they aren't quite as fast as others. HomePage
- SL Variant makes some of the most expensive speedloaders there are and many people love them. They also are adjustable in some ways for tension and load the cylinder by just pushing on them. They are are made in Germany and very high quality- I only have a couple of them in K-frame size .38 and love them. Extention handles are made for them too which help in competition or range shooting. They are fairly secure and wouldn't be worried about them at all for concealed carry use. The feller that is bringing them into the U.S. is Bobby Mac, and I've bought two of them from him so now I have three. The only disadvantage to these loaders are they are more expensive than the HKS, but they load so much faster. http://www.bobmacs.com/variantcatalog.htm
- Safariland speedloaders are great because they are inexpensive (at least they used to be) and they load the revolver by pushing on them instead of twisting them. They have three different models which are the following: Comp I (for use as concealed carry because of its low profile), Comp II (which has a larger knob and completely covers the back of the cartridges for a better look or to keep debris from entering the speedloader on a duty belt), and the Comp III (really a range or competition loader). The big drawback to Safariland loaders of late is that they have discontinued many fitments of various revolvers. Also, some competition shooters I know have complained because the plastic used in these speedloaders is not as tough as others and the little piece that holds the catch tends to wear smooth and the speedloader "wears out." Of course, most people never wear one out, but if you use it a whole lot (weekly) I guess it's possible- I haven't yet. Duty Gear | Speedloaders | Speedloader Holders - Safariland
- Jetloader Speedloaders imported by Buffer Technolgies is a great loader. I picked up two of these at the local shop for my J-frames and really like them. They are made in Austria and seem to be of a tougher plastic than most others. They are almost a Comp III on steroids (Comp III's have never been made for a J-frame). They make these for J,K, and L frame S&W's and are more affordable than the SL Variants, but very high quality. Loaders @ Buffertech
- 3D Inc billet aluminum speedloaders are some of the nicest and likely tough ones money can buy. They function like that of an HKS, but are a bit more stylish and likely, tough. The knob is a bit easier to turn because it is larger and the flutes on the side of loaders help to locate the charge holes on the cylinder. They make these for many various pieces in calibers and frame sizes all the way up to the .500 S&W! 5 Star Firearms Home | Firearm Accessories | 100% American Made
- There are various antique speedloader designs out there, such as the old "Revolver Clip Cartridge Company" folding speedloader (which is neat, but very expensive compared to others if you find one), Prideaux loaders in .38 and .455 (several hundred dollars) so if you find one or two of these, they are worth more than for their use. Colt and other companies made them too, but they are very rare and not very useable, even if a person can locate or afford them.
Now, on to moonclips!

Moonclips can be adapted to almost any centerfire swing-out cylinder revolver. All that has to be done is send off the cylinder and yoke/crane and have it machined to take them. Even once machined moonclips do not have to be used, but make loading and unloading much easier. If you reload, the brass will stay in the moonclip for easier retrieval if you just drop the whole thing on the ground. Clips are cheap enough that if you bend or break one you won't fret about it too much (unless you're a tightwad crumdungeon like me). The only problem that will be encountered is that machining cannot be performed on old style "recessed" cylinders.

Wait, I forgot a couple!!!
- Maxfire speedloaders- these things are silicone rubber and very light and work by holding them by the ring and then pulling down on the loader in order to "wipe" them off into the cylinder. Great for competition, but if dropped they rounds tend to want to come out of the loader. They are inexpensive, since they are around $14 for two of them. MAXFIRE
- Thunder Ranch 8-shot N-frame .357 speedloader. I don't know first hand about it, but have read reviews and it seems to be well made. I think Thunder Ranch is the only place they sell it, and it isn't made to fit any other firearm. Looks neat though, but at $65.95 it's the most expensive single loader currently made.
If I forgot anything else that needs to be mentioned, let me know.
