I bought the SR in a 28 ga s/s and have ran roughly 600 rounds through it on the clays range without so much as a hick-up. Maybe I got a good one don't know but I like it so far. Light and shoulders perfect for me.
After I posted this I did think of one thing that was a problem when the gun was first shot. When the gun was opened to eject the empty cases unless I opened it fully to allow it to cock again I did get a misfire. However once it was broken in a bit and loosened that problem disappeared completely.
The Silver Reserve is made by Khan in Turkey, I would pass on them. I had a Khan O/U and the thing started to double with less than 50 rounds shot through it. A guy I work with had one and the firing pin broke with less than 100 rounds through it.
I do know another person that owns a Silver Reserve and he is happy with it, but he doesnt really shoot it.
