I have various 9mm revolvers. I like to shoot revolvers and I don't reload, so I use them often. In no particular order...
Ruger SP101 - They don't fit my hands well, but with the right grips I can manage. The moon clips are very easy to use.
Ruger Blackhawk 357 with convertible cylinder - Works fine. Mine is kinda large, with the 6.5" barrel. I picked up a 9mm cylinder on ebay that happened to fit and work just fine.
Cimarron "Pistolero" by Pietta - Better size to carry around than the Blackhawk. Smaller frame and 4.75" barrel. The much smaller sights make accuracy a bit more challenging than the Blackhawk.
Alfa Proj - It's a medium-frame DA/SA and thus pretty good for practice for my HD revolver. The sights are oddly tall and the DA trigger is way too stiff. As soon as I find a mainspring I will rectify that. It's okay. It goes bang. It's about as accurate was any other medium-frame 3" revolver.
Taurus 905 - It's a j-frame snub in 9mm. The moonclips are like the SP101 kind and are easy to use. The DA trigger was stiff, but I replaced the mainspring and it's fine now. It shoots like any other snub revolver.
They all work fine. The Rugers are kinda pricey. I felt that the Alfa Proj was worth the $399 or whatever I paid for it, but I wouldn't pay more (it's really not as "nice" as a Taurus). The Italian SAA replicas are affordable and a very good option if you like SAA. The Taurus 905 is a good choice for anyone who likes to shoot snubs. It shoots like any other j-frame and is affordable. As far as I can tell, it's just a Model 85 in 9mm. They've been making that model since the mid 1980's. I wish I had bought a Taurus 692 some years back when they were easy to find and relatively cheap.
9mm is a good caliber for revolvers. A little spicier than 38 special, but not obnoxious. The SA revolvers don't need moonclips, of course.
My average range trip is just 22lr and 9mm these days. Very affordable. Practice with the 9mm revolvers transfers just fine to their 38/357 equivalents.
