Auto, over/under, pump and even a sigle shot will work great, My dad used a browning A5 in 12 gauge which I have now. But for all my upland hunting I use a Stoeger Condor over/under 20 gauge, my son uses a Remington 870 pump in 20 gauge, and my daughter uses a Mossberg 500 pump in 20 gauge. I like the 20 gauge to upland hunting. If that A5 is at a good price, snatch it up
