Keeping in mind you have to strip clean them due to the salt spray & mist. I'm thinking maybe a double or O/U but you have to always break them over the blind front ect. Looking for a better mouse trap.
As Mdl No 12 suggested an inexpensive pump, with synthetic stock & forend, would make sense. Disassemble it and thoroughly wash it with hot soapy water when your done for the day to remove all of the salt. Make sure it's dry and wipe it down with an gun oil impregnated cloth. It should last a long time.
As a youngster I carried an A5 Browning until it needed detailed cleaning. It had to go to a gunsmith that recommended detailed cleaning every year. I then bought an 1100 Remington that I could knock out two pins and get to everything. When steel shot became the law of the land I bought an 870. Soon after that with disappointing experience with early steel shot loads I gave up duck hunting.
i use a stoger 2000 and just spray it down with rem oil after every use and once a month or so take it all apart
extremely easy to break down just unscrew the cap and knock out the one pin for the trigger
Im a fan of cheap guns in the duck marsh just this weekend my buddy was carrying my gun and dropped it in the mud its going to happen
i would rather use an 870 but im no good with a pump
If you want a good duck gun, you should have the Parker DHE #3 frame, 30" raised rib barrels, choked F&M, single trigger, ejector gun that is in my safe and is looking for a new owner. The great thing about this gun is, even when you miss you'll look good.
I hunt in these areas all along the east coast. I usually hunt from layout boats. Hands down, the best shotgun for this is a Beretta Extrema. While its nice to hunt with an o/u or classic double, the shells used for these birds are extreme in the demands that they put on a firearm. Best to have a gun that is corosion resistant and equipped with choke tubes that handle modern waterfowl loads.
It is clad with metal inside of the chamber and barrel and uses Remchokes. The only thing I had to get use to not short shucking the action like my Wingmaster and Express it has to go all the way back. I love the gun and it gets better every timg I use it.
