Several folks have spoken well of these. I realize it is not a Purdey, or even an AYA, but for a field gun that probably won't be shot all that much (1,000 shells a year max) I wondered if they might be just fine. Are they really as light as advertised, 5.2 pounds? If so, can you keep it swinging smoothly? How about recoil? Had any problems? Thanks!
