Ruger quality control has been on a solid upswing since at least around 2004. The mid-frame SAs (New Vaquero, Montado, 50th 357 Blackhawk and the new 44spl) have been gems. They did have one minor-issue recall on the first batch of New Vaqueros (under SN5000ish, mine is just over).
Ruger did something very smart and tested the internal keylock on those single actions for literally years with zero failures before shipping it on a gun more likely to be pressed into a defensive role (the LCR).
As to "worrying" about a recall...why? Ruger has always paid shipping both ways on recalls and often thrown in some nice freebies. And as stated, Ruger is handling issues under recall when Taurus in particular should have done at LEAST three times the recalls in the same period, and didn't, forcing people to pay shipping going in and often not fixing problems the first time out.
Just the *ideas* behind the LCR are revolutionary: fix the trigger, set it up DAO from the get-go and take advantage of the grip placement options that gives you, oversize the triggerguard for gloves (YAY!), pinned front sight for easy upgrades, good old fashioned steel in the cylinder (even if it is cut funky), more. And it appears to be all panning out.
