Ruger made three different 9mm revolvers that use moonclips.45 ACP, 10mm, and 9mm NATO rounds are the only ones using full or half moon clips(3 rounds) in revolvers. The only 9mm revolver shooting the 9mm load was one made several years ago by Ruger and is now discontinued. If my memory serves mne correctly, Ruger received a large order for 9mm revolvers from a European country (France?) and also offered them to the public for a few years. See them on the used gun market every once in a while.
Supposedly they're going to offer the new BodyGuard revolver in 9mm this fall. Check out my thread on the S&W forum - http://smith-wessonforum.com/s-w-re...g-believe-what-s-w-rep-told-me-yesterday.htmlThe S&W 940 is a Centennial J frame that shoots 9mm with 5 shot moonclips. Great gun just a bit heavy. Some tended to have hard extraction, a bit of polishing in the chamber normally solved the issue. I have a 940 cylinder installed in a 642, making a 942. It would be a great gun if S&W started making one.
I've got a 1917 S&W revolver & it uses the moonclips, I just carry a reload in my pocket with no problem, btw this pistol works great with the 3rnd moonclips also.
