The Ruger would be my choice.I have a early production 20 ga.Really a nice shotgun.I just wish it had the screw in chokes that came out in later years. Mine is choked SkxSk.If there should ever be a problem Ruger will stand behind their products.Parts are always available if needed.To me that means allot.I always wanted a Browning Citori but never did.If the Ruger fits you ,I would say go for it.I think you would be more then satisfied with the quality and performance.Hopefully one day I' ll break down and buy a RL in 12ga.Watch
www.gunsamerica.com there are many listed NIB at reasonable prices.
