Yes, you'd have to worry about timing, and I don't think Ruger would do it for you, which means you'd have to pay a smith. Then you'd be way upside down. I'd wait for a 357 to come along--there's usually one or two at most shows. Around here you could get a stainless Sec. Six in great shape for $375--a little more if you want 6" or with an original box and you'd have adj. sights, but the square butt like the Serv. Six.
