Onpoint;
First let me start of by saying my dad is an O/U nut. The reason I say that is that there are not too many O/U's that I haven't shot due to his obsession. I have personally hunted with an Ithaca/SKB 500 20 for the last 20 years or so. My dad had the Cynergy Feather 12 and did not like it so it ended up in my safe. One day we were in Gander Mtn. and there was a Cynergy Feather 20...same story; he bought it, did not like it, I snag it.
Once you get past the modern styling and non traditional grip, (IMHO), the Cynergy Feather 20 is the best handling and shooting 20 I have ever had. It is an absolute joy to carry in the field and comes up to the eye like no other. My Ruger RL 28 is close but the Cynergy is the real deal. I have many shotguns to pick from; but when the serious hunting is on, the Cynergy is my go to gun. You will not be disapointed. My only warning on the Cynergy is, be careful when the spent shell ejects...those babies come out at Mach III speed. Took one off the cheek one day; ouch!
To prevent any argument, this is not a Browning advertisement nor a Beretta bashing. My favorite auto and dove gun is an old Beretta AL2 20. My sons have (borrowed) all my Benellis, and one of them swears by the Winchester SX3; and who doesn't have an 870 or 1100 lying around, so don't yell at me.
By the way, my dad has two old Charles Daly O/U's; a 12 & 20 that he always goes back to. Both are Miruku built.
Back to the original question: buy it, you won't be disapointed. Not sure were you are or you could try mine. Good luck with you choice.
