My buddy is looking at a Moss. 935 (turkey/waterfowl combo) comes with 24" & 28" barrels (advatage camo) w/ red dot scope for 499.98. Or Moss. 500 (advan. camo) (T/W combo) 22" barrel with xx-full turkey choke and 28" field barrel, with red dot scope for 299.98. Do you think these guns are any good? Prices any good? I gave him my opinion, now we'll wat for yours!!!! What's the difference between 500 & 835?
