I'm gonna do what longrifle did... since its what I usually do.

1. Is that a good gun (price range) compared to the Browning Gold/Silver, Mossberg 935, Franchi I-12, Stoeger Model 2000, and the Beretta Urika?
In order, No, Yes, Nope, No Way and Not even close.
2. Is the gas system better than the inertia systems?
I like the way longrifle answered this one. Yes and No. There are gas operating systems that work VERY reliably. Such as the orginal 1100 and the 390/391s. The inertia drives do have more felt recoil, and because the guns are light in weight... its even more than normal.
3. Does the difference in the 28" barrel and the 26" barrel a noticeable difference?
That depends on if you are talking about speed (no) or shooters perception (yes). If you have been shooting a 28" barrel your whole life.. don't switch. That can make a big difference.
4. Will the 11-87 Super Magnum shoot ALL rounds? Does it shoot the lower brass shells? I heard someone say the gun comes with 2 O-rings that can be swapped and both shells can be shot...I dunno...
I have never seen an 1187 Super Mag shoot everything. Infact I haven't seen many remingtons made lately that shot anything reliably. If you are getting a supermag gun... get it to shoot super mags... don't try and shoot 3 dram shells with it. Thats like running 87 octane in a top fuel dragster.
I would take a hard look at the Stoeger 2000. Also, I'd look even harder at a new Beretta 3901 (statesman or citizen) or a used 391 or 390. Most can be had (esp the 390s) for under $600.
Thanks for time to comment!
Thats what we are here for. Good luck!
