Your opinion on the Beretta A400 and the Browning BPS Trap? I have a synth. 3901 28 inch barrel for everything (doves, ducks, all clay target games, and turkey. My daughters required removal almost 2 inches off the stock of an old Browning Gold with a target gas piston that shoots ok but cleaning is required more than the 3901. I can shoot it with a slip Pach. recoil pad with a lot of cardboard inserts for length of stock.
I’m not really sure what your question is. The A400 is a nice auto, but I don’t think that it’s any better than the 391 or the 390. Your 3901 (basically a 390) is an excellent gun. Reliable, versitile and ideal for what you are using it for. Unless you really want a new gun, the 3901 should be all you need.
As to the BPS trap, I’d definitely get an 870 trap before a BPS trap. I’m not a big fan of bottom ejection and I felt that the 870s were smoother than the BPS, at least the ones I’ve had of both showed this. Either one would be a buy as a used gun as these pumps never wear out.
As to the Browning Gold, what can I tell you. When you cut the stock for someone, you run into this sort of thing.
