I am planning on eventually getting a semi-auto shotgun for home defense once I am out of school. A 12ga is the only type of shotgun I have ever shot. I found it pretty powerful and it took me significant time to line up the next shot due to the recoil of the first shot. I was wondering how much less powerful a 20ga is. Is it something you can get fairly rapid shots off with on a semi-auto shotgun?
I am no expert either, but the 20g I fired seemed to have a lot less recoil. Regardless, why do you need to fire mulitple shots quickly? I have a 12g for home defense and cannot see why I'd need to quickly fire off a lot of rounds, unless my house was being attacked by Zombies. Then I would need to FOR SURE

For self-defense pump action is plenty fast. If you shoot your home/personal defense SG enough as you should in order to safely rely on it to protect your home, racking the gun becomes second nature and can be used in conjunction with the recoiling SG to cycle smoothly, recover, and engage your next (because your first target shouldn't need a follow-up) target.
Semi-Auto shot guns are very useful in shooting sports. i.e. trap, skeet, sporting clays.
One exception would be if (and you may be) this question is in reference towards a Saiga. If you have one great, use it, but if you are considering one for a home defense SG, look around. For what you'll pay for a Saiga, you can get quite a package (maybe close to 2) for a Winchester 1200, 1300 or 1400, Mossberg 500 or 590, Remington 870 and much more and they eat EVERYTHING!!! Plus modification is a blast!
The recoil is totally dependent on 1: The weight of the gun, 2: The weight of the load (oz of shot) and 3: the velocity of the load (fps). There are many 20ga loads that equal 12 ga loads (example, 1 oz loads are typical for both 12 and 20ga) and with an equal weight/action gun they would recoil the same. A gas operated semi-auto will recoil less than a pump of the same weight as some of the propellant gasses are bled off for the action. There are lighter weight 20 ga loads available, but for self defense almost all are maximum load rounds and will recoil as hard as any 20ga rounds will, and close to what the 12ga recoils. Sometimes the 20 ga will even feel harder as some of the guns are built lighter than their 12ga equals. Bottom line, for self defense the recoil will be similar, but for hunting or target shooting you can use reduced loads (in both the 12 and 20) for less recoil.
