^^^ What he said.
Wolff Springs sells replacement spring kits - stock number 17116.
The loading gate is typically the biggest gripe I hear - it is a PITA to open.
I'm told Single Six, Blackhawk, and New Vaquero grips fit, as well as spring kits for SS, BH, and NMV.
The company literature says it's ok to dry fire - DON'T. It will cause damage in relatively short order and result in failure to fire. Ruger, however, will replace the damaged part (cylinder IIRC) at no charge.
I have found, through limited experience myself but other shooters as well, that Ruger typically has great customer service.
