Looking to get the S&W 610 4in soon as my Disability check gets oked for new claim, looked at super Redhawk tooooo big, Blackhawk ok have to change cylinders. S&W use moonclips for 40 and 10 which I already have for 357. Will order new moonclips and some 10mm brass. Used to shoot 10mm had a Kimber and dan Wesson razorback sold both like a fool. now alittle older and alittle smarter at least with the smith I wont have to chase brass.
