you could buy one nice double barrel or two budget guns (a 2x bbl and a pump).
a cheap century double barrel is $279. a cheap (but good & popular) budget shotgun is the mossberg 500 or Remington 870, at $300. still cheaper than a nice double barrel - $800 to $1000.
besides, those nice double barrel guns do not look as badass as a cheap century/chinese import.
most double barrels either have two triggers, it would be difficult to pull them both, if you did the recoil would be heavy. it would be very sharp resulting in bruises and a very sore shoulder, but there's not alot of recoil... by that i mean recoil (like most things) can be measured two ways: speed of recoil vs depth of recoil. speed is how fast or heavy is the jolt of recoil, depth is 'weight' or how deep is the recoil.
shotguns are on the extreme end of sharp recoil. is the gun's also heavy it'll be sharp and heavy. blackpowder and muskets are on the other end, having deep but very slow recoil so it's perceived as very light.
a double barrel shotgun would have very very sharp recoil, but since the gun's not very heavy and the powder burn time is very fast, it will have less depth of recoil as compared to say, a 30-06 rifle...
