that's why they invented Scandium
340/360 PD or SC, depending on your taste in color/finish. About half the weight of the Ruger--11 to 12 oz, and capable of full-house 357 Mag. No, it's not fun to shoot, but there is one THR dude who has 26,000 rounds on 357 Mag through his. Tell me again how Rugers are "better built" and "tougher"?
As far as carrying it goes, "Anytime, anywhere." In the pocket, on the ankle, any way you choose. Forget that it's there, and never be without it--isn't that the point?
Oh yeah, they are pricey brand new, but they are out there for a reasonable price...some have been fired a cylinder or two worth, and someone's sore hand traded them in. Too bad...for them. I'll live with a sore hand from time to time in exchange for something I can always carry...and I guarantee it hurts a LOT more at the other end.
