No, 12 gauge receivers have a larger diameter, the higher the number, the smaller the diameter

from $100 to $400 depending on condition and barrel.
No, a 12 gauge Remington 870 barrel will not fit a 12 gauge Remington 1100. The two shotguns have different designs and systems; the 870 is a pump-action shotgun, while the 1100 is a semi-automatic. Their barrel attachment mechanisms and receiver dimensions differ, making them incompatible with each other.
To my knowledge the 1100 Tactical is only available in 12 gauge. The 12's can be had from about $700-$800 maybe a little less. I paid $675 for mine at a gun show in Las Vegas
Ithica made the '' deerslayer" not remington
The Remington Model 1100 shotgun is still in production, hence it would be worth no more than list price - and probably less, if it has been used at all.
