Well I carry a Sidearmor IWB http://www.sidearmor.net with a sweat shield. I love the holster, carries very well, holds the firearm well, and protects it from sweat. Though they don't make a holster for the Steyer or Ruger.

You might want to check with G-Code, I know that http://www.gunnersalley.com/ carries that holster, not sure if they make it for your models though. They are great to do business with though, if you e-mail them, they actually answer back in a day, they could help you.
