I have a 20g. GDR Merkel. I think it's a better gun than the newer ones. The importer at the time told me that this particular gun was a special request for a light weight and consequently came in at 5 lbs. 13 ozs. Maybe they spent a little more time on it but I've never seen better fitting on any gun. Also of course the action design was changed on the later guns. It became longer and the internals were also changed. Merkel naturally said the change was to improve the design. Usual BS. It was really done for ease of manufacture, an improvement in their minds maybe.
