I've had this sr410 for two seasons now:

i believe it is steel and it came with screw in chokes.
I am a huge fan of it.
people complain about the price of 410 ammo, but i'm conditioned by my marlin 45-70, so the 410 doesn't feel that bad to me.
I love how it is light to carry, easy to use one handed, and easy to fit in a pack.
At the range i find it hard to aim because it is so short. But when hunting grouse, when i see the bird i shoot first and think second, and i find when i just let my reflexes aim and shoot like that, my aim is much better than if i took the time to think about it. Come to think of it, in 2 seasons i think i've only missed one shot, and one of my succesful shots was literally from the hip. I should clarify, i'm usually an average shot at best, so my point here is that it's easy to shoot.
those are the pros, i'd list the cons but i honestly can't think of any.
