I own a Ruger security six 4" 357 mag (1979). I was wondering how 9mm ammunition shoots out of a 357 mag barrel. Is it safe and how accurate is it? If it's worth it I was wondering how easily my security six can be milled to use 9mm moon clips and how that would effect shooting 357 mag/38 sp. Also how much would it cost if it can be done?

The Air Force tried this 40+ years ago with their S&W M15s. Accuracy was terrible, and it also requires rechambering the existing cylinder. As a result, .38 Spl ammo can still be fired, but the brass swells to fit the hybrid chamber. My advice is to invest in a dedicated 9mm revolver, if that's what you really want.

If I got another revolver it'd be a Ruger/S&W 10/40 double action and I'd likely sell the 357. I would rather stock less rounds. I got a XDM Elite 10mm 4.5 with springer comp and 507Cx2 Vulcan and a Glock 23 which I intend to buy the conversion barrel so I can shoot Glock 19(9mm magazines out of it).

I like the 357 mag, but out of a short barrel it's virtually identical to the 10mm.
