I am a Double newbie and have experience owning only Merkel rifles.I remain curious and confused regarding the specific differences between "best" quality rifles vs higher end entry Doubles such as Heym and other Double manufacturors.

Obviously "best" quality rifles have more labor/time with metal/wood fit and have engraving etc.The ?timing of their internal parts function is proper etc.The Heym appears to have great quality of manufacturing as well.

Would someone please inform me in my ignorance regarding the specific judging of the quality of a Double rifle feature by feature.What is different between a higher end Heym or similar Double with engraving and a "best" (name hidden)quality Double??

Thanks to all for any info which can enlighten me further.
