Sure. HKS does. I have 2 in my coat pocket as I type this. Its the same one for 32 H&R mag, product number is 32-J and it works in my S&W 432 and my Ruger SP101
HKS makes them but I prefere the Safarfiland Comp 1 model# c-7j is for the j frame .38 spl. They may make one for the .327 Fed.Mag I'm not sure .The think I like about these is that all you have to do is push down on the speedloader and the back of thr extractor pin releaces the cartriges and they sort of "shoot" into the cylinder as oposed to having to twist the release knob .There much faster and easies to use under stress .There not on the web sight in .327 but it's kinda new so give them a call the # is 1-800-347-1200
Safariland are faster... when they work. When they fail, as I have seen at competitions and in informal sessions at the range, then they are MUCH slower...
