You got some good advice from some of the above posters!
I have been hunting with an 870 Express 12ga. since the early 90's. Under some wet conditions the finish will get surface rust that easily wipes off with a rag and some gun oil! The metal surfaces still look great and the gun has never failed me!I have a rifled slug barrel, as well as a 28" vent rib barrel. With those, you can do any Jersey hunting.
Regardless of whether you get an 870 or Mossberg 500, get a 26" or 28" vent rib barrel, and a rifled slug barrel. I would recommend a cantilever scope mount over iron sights. With the cantilever scope mount, your scope is on the barrel and the barrel can be switched out and back with little to no change in zero. I didnt recommend iron sights because hunting hours in NJ for deer are 30 minutes before sunrise to 30 minutes after sundown. You will see most deer during this time period at the beginning/end of legal hunting hours. A scope is easier to use during this lower light period! Also, if you do go the scope route, dont buy a cheap scope, a good $150-200 scope will hold up better, have better light gathering than a $40 scope will.
Good luck, welcome to hunting!
CZ 97 B
Full Size (4.75" BBl.)
Two (2) 10rd mags
The CZ 97 B is the big-bore brother to the CZ 75 B, the first CZ pistol produced in .45 ACP.
It is operationally identical to the 75 B (SA/DA, firing pin block safety and magazine brake).
Features include a screw-in barrel bushing, loaded chamber indicator and a double-stack magazine holding 10 rounds.
Thin aluminum scales slim the grip down to make it comfortable for even those with smaller hands,
and the fiber optic front sight and two-dot rear make it great at the range.
