Do those 9mm revolvers need moon clips?
Some do, some don’t. Those that don’t require moon clips include:
1. Charter Arms Pit Bull
2. Korth Sky Marshall (I think there are 2 or 3 models from Korth)
3. S&W Model 547 (No longer made)
4. Ruger Blackhawk 38/357/9mm (Intercahngeable cylinders - Single Action Only)
Revolvers that require moonclips include:
1. Ruger Security Six/Speed Six (No longer made)
2. Ruger SP101 (No longer chambered in 9mm)
3. Chiappa Rhino (They have different models)
4. S&W Model 929
5. S&W Model 986 (Currently for sale at a great price here:

6. Taurus Model 905 (I think there are a couple of different models)
7. Ruger LCR
These are all I know of. I am sure there are more.
Technically speaking all (or most) 9mm revolvers can be loaded without moonlips as the 9mm cartridge headspaces on the front of the case. Unloading them is another matter. I frequently shoot my 9mm revolver that requires moonclips without using the moonclips. I glued a wooden drawer pull to the end of a 1/4” wood dowel and I use it to poke out the empties.
