I think Box-of-truth has done tests like this.
EDIT: Tests on penetration between buckshot, bird shot, and then a separate test of 5.56 penetration.
If you can find one, an old Ithica model 37 ( wish I never sold mine years ago ) is fast on follow up shots, pull and hold the trigger down, shuck the action and when the round seats, the next shot is on it's way. You can empty the mag tube as fast as you can shuck the action.
As for the safeties, both the 870 and Ithica are not southpaw friendly. I always seem to push it toward the safe position while firing.
I will order a lefty safety for the next 870 if I get one.
All good advice above. my preference is for the defender also. Noticably faster close to a semi. I prefer 20 gauge. Good luck finding a 20 defender. I like the 870 20 youth also. It comes with a 21" barrel and choate makes a extension for it. Cofi makes a good point about the 5.56 but look at the decibal levels. Shooting a 223 outside without hearing protection is painful. Inside... A 20 Has significantly lower DBs. I run slugs. no light tritrium bead.
