The FW (Featherweight) gun is distinguishable from a Regular frame in that it has two screws on the left lock plate and one on the right plate. The Regular frame has only one screw.
Also not all FW framed guns are lighter than Regular framed guns having the same specs.
The "E" on your gun is for ejectors. The frame has nothing to do with ejecting, it is all in the for-end.
Correct, this is a FW frame, the screw patterns match, the smaller barrel lug, etc. But, it is a fairly light gun for a 28" 12ga SxS. My NID seems much heavier, although it does have 30" barrels. I need to weigh them.
Either way, happy with the gun, plan to shoot it this weekend.
