Gerneral Purpose Shotgun...
I must be the only person on earth that has not handled or seen a real live a Nova yet.
I've been a little busy, pre-occupied, and I guess I must admit a bit slow to change to new stuff. IIABDFI kind of guy.
I'm big on gun fit, my understanding is the Nova does not lend itself to tweaking the fit to a shooter.
I'm big on proven reliability, availability of parts, availabilty of those things which I may need to tweak the guns to my needs, and ease of maintenence. So I lean toward the Big 4...like I said, I have no experience with a Nova.
I actually like the old 97's, model 12 Winchesters, and the Ithicia 37...nowadays, for the price of week's pay and all...I have my druthers from one of the Big 4. Okay I have a favorite.
Sights...well I learned to shoot without crutches, be it rifle, handgun or shotgun...I learned to shoot without sights. Comes in handy if a bead comes of in the 3 rd box of a big tournament, in the middle of a bird hunt. I still came in 2nd, even without a bead, beat fair and square going into the 2nd box of a shootoff, my fault, not the guns lack of bead, I didn't have my hold point right, let the bird get ahead of me, I messed up my timing. I still limited out on quail, doves, and ducks tho without a bead.
I have an easy 100k rds thru one shotgun alone, I have used it for everyhing, it has a front bead and a mid bead. I have easily put another 100k rds thru a few others with only a front bead, so for me -on an all around shotgun I don't want a rear sight.
I don't
AIM a shotgun I
POINT it as it was intended.
Slugs for deer, a stationary target, a rear peep with insert removed is great. For those with aging eyes, and slug shooting the Ashley Express is great. I think this is a faster system for 3 gun and LEO use as well - personally. Aging eyes and bird hunting, target shooting white paint, green paint , hi-vis green, Bradley, or Asheley front only helps them.
But folks have harvested too many deer, shot too may perps in real gunfights using only a front bead. Some of these real deal folks learned to shoot without sights as I did...If they lose the front sight going after a deer, or in a real gunfight...they will be okay.
I'd rather not learn on a crutch, and have nothing to fall back on. Comes in handy when you knock off the front sight of a 1911 / or revolver in a match, or training deal.
Besides, GR get in my way laying on the ground , rolling in mud and dirt trying to shoot over my head back at a target with someone dragging me the other way...[ simulate me being rescued and giving cover]. Damn GR bumped the side of stretcher on that simulation as well...nah leave my rear of shotgun free and clear.
