The Benelli Nova is a decent pump gun / but there are 2 versions the Nova and the SuperNova. List price new on the Nova synthetic is $409 / $499 on the super nova synthetic - and add about $100 for the camo finish. There is a big difference in the guns - with the Super Nova having the Comfort Tech recoil supression system in the stock - and I like that system.
Nova's and Super Nova's come in 24", 26" and 28" - and for hunting or casual Skeet shooting the 26" might be ok / but the 28" would be a lot better - because the longer sight plane will give you better follow-thru on a moving target for hunting or Skeet. A 28" barrel on a pump or semi-auto will give you about the same overall length in a gun as a 30" barrel on an Over Under.
The 28" barrel version also gives you a gun that is around 8 lbs - which is a plus - heavier guns follow-thru better and they absorb more recoil than lighter guns. Most people that shoot lighter or shorter guns - find they have trouble keeping them on the plane of a moving target / and they get a little to "whippy" vs a nice solid feel.
Personally, for an Over Under, I like a 30" barrel ( and a gun that weighs about 8 1/2 lbs ) for upland bird hunting, Skeet and Sporting Clays.
But the Nova or Super Nova are decent guns / although my personal preference in a pump gun is the Browning BPS Hunter model - also in a 28" barrel.
The problem with all pump guns - is the angled stocks they have on them ( the 870's and the Browning too ) have a lot of drop at the comb and the heel - and they aren't really adjustable. You will find an outfit - a vest, over a windbreaker, etc - that will put your face at the exact spot on the comb - so it shoots where you look. If you shoot in a T shirt / it moves your face forward on the comb - and causes the muzzle to move up or down - and it changes your point of impact. Putting a stick on pad on the comb - can fix it - but they're ugly ... and don't stick too well ...
So fit on a gun with an angled comb is critical - and they don't come in one size fits all. I don't recall one there in the 70's when my ship was in Kodiak - but if you have a Skeet or Trap field on the base - spend some time out there talking to shooters and see what kind of guns they're shooting. My CGA class was '74 ....I'm just a cranky old bas---- now .... / good luck to you .....and have some fun picking out the right shotgun for yourself.
