I have the Orion 20g in o/u ,I had looked for the SXS but none were around now I see them pretty much everywhere,however mine has worked flawlessly for the past two years with over a thousand rounds through it.Some have been heavy 3" as well as I use it for early duck season still performs so the build quality I believe is there even if its not a SXS .My only ##### is the barrel /safety selector is a poor design as it has locked up while trying to get the safety to disengage ,me or the gun ? but something you would not have to worry about with dual triggers.
