I have a Winchester Model 12 for bird hunting - it's my favorite. It's older than I am and functions flawlessly. I have a Mossberg 500 for HD. Both are great shotguns. I had a stock Saiga 12 that I sold about 8-10 years ago - still kick myself over it. I plan to buy another one - that shotgun was a blast to shoot.
My favorite is my Winchester model 1300 - pump 12 ga. Shoots smooth. I've used it for rabbits and squirrels, though I've just picked up an H&R 410 single shot as my 12 and 20 are tearing things up too much. I like to carry a .22 rifle, but this time of year there's too much foliage on the trees - all you see is bouncing branches. I'm hoping the 410 will do the trick.
Got to be my Wingmaster.
Only shotgun I ever got rid of was a Marlin Super Goose 10 ga. You haven't lived until you've shot a bolt-action 10.
Wish to own?
Wouldn't mind getting a Saiga. Just something about an AK-style shotty with a drum mag.
One of the nicest Shotguns I ever laid eyes on was a Winchester 23. I couldn't afford it at the time, had to settle for a Browning BSS. Now days I am equally happy with my SxS's and I compete with a TTN Colt 1878 Replica and hunt upland game with a Laurona SxS, made for Sears.
It may not have the sex appeal of the Winchester 23, but it still functions very well.
I have owned two Mossbergs, a New Haven 600AT (still have it) and a Maverick 88, both 12 gauge, and I loved them both. I also have a winchester model 1200 12ga, but the mossbergs just feel better IMO. Love the two Benelli photos above. Those look pretty cool.
For home defense - I have an H&R Pardner Protector. It's an 870 copy. I have a pistol+stock rear on it, and the small round grooved forestock. Both stocks are poly. It has the standard 5 round mag. I have a push-switch multi light that includes a spotlight, laser, and strobe. It's mounted on a top rail at the rear.
The gun isn't pretty. The flat black finish is thin and poorly applied, but I didn't buy it for the finish. It's accurate and reliable with a moderate recoil. It's a moderate-weight gun. The price at Dick's was very reasonable at around $200.
