Smith and Wesson have reissued the 610 N frame in 10mm/40. 4" and 6" or maybe 6.5". Since 40 cal is hugely popular in autos and 10mm seems on the upswing, it would seem a better choice than the 41 as a medium bore. I own and love my 41's, but they aren't that popular and choices are limited with regards to guns and components. Make an autorim and and you would have a practical and versatile bunch of options. I use 10mm start loads in my 41x1" and its a peach in my Mountain Gun. On thse rare days when I'm not blastin' big bears or cappin' suicide bombers in cement trucks, I think I have the power for most other applications. I like the revolvers mainly 'cause I don't want to chase brass and the greater range of loads the wheelgun can handle. But i would like the option of clips or not, a la 45acp/45 autorim.
