With the 20 gauges I have, average around 6 lbs. 4 ozs, yours is just 6 ozs heavier, no big deal. If you like everything else about the gun I sure you will overcome what others think is heavier.
Like I posted before, I don't know where some of these people find these 5 lb. 6oz. 20 ga. and 6 lb 12 ga., I wouldn't want to shoot them. Nice to carry.
