Marine shotguns

Their DLC (diamond like coating) and salt fog testing is interesting. However, you'll notice they spoke about chrome lining every barrel they manufacture. Chrome finish is the superior corrosion solution. Alternative processes for external "marine" finishes are about cost and ease of manufacture.

To stick to the OP topic, Winchester is the only manufacture I am aware of to pull out all the stops and factory produce a completely hard chromed triple plate finish "marine" purpose shotgun (1980's model 1200), using 100% the best known finish for the application over the entire gun.

Hard chrome is swesome.

However one of the reasons you don't see more fully hard chromed factory guns is that hard chrome plating is thick enough that you probably need to redimension at least some of the components if you want a functioning gun, with all the extra logistics hassles that entails.

Even comparatively thin finishes like NP3 can cause issues at times.

Only one I know that actually came in hard chrome was the Winchester Model 1300 Stainless Marine

 
It’s in the name. Stain-less, not stain-proof, or rust-proof.

Stainless steels are an iron alloy and corrosion “resistant” because of the high percentage of chromium mixed in. Other elements comprise of nickel, molybdenum, titanium and others. All have excellent corrosion resistance, but will eventually oxidize, stain, corrode, rust and pit over time. Not to mention inclusion of carbon.

The Winchester Marine Defender is a good option. Nothing is perfect but this is one of the better options.

From NRA Shooting Illustrated. https://www.shootingillustrated.com/content/winchester-super-x-pump-marine-defender/

The SXP Marine Defender's most intriguing and visibly striking feature, however, is the hard-chrome plating, designed to fend off the corrosive nature of damp and possibly salty environments. Chrome coats the 18-inch barrel's exterior, the magazine tube and the action bars. The barrel and chamber are internally plated as well.

I have a SXP Marine Defender, it is surely a beauty. No idea how it does with resistance to corrosion as I don’t live by the sea and probably wont be taking it onto a boat any time soon.

It was the Model 1200. Stainless Marine, and the stainless police

It’s a bit confusing the way Winchester rolled out those names. In the early days it was the “Winchester 1200 Stainless” (polished) and the “Winchester 1200 Police” (matte). Then they switch the names to just “Winchester Stainless Marine” (polished) and “Winchester Stainless Police” (matte). All were triple plated, only difference is one was polished prior to plating and the other was bead blasted prior to plating.

Then there was the “Winchester 1300 Stainless Marine”, which had a black hard coat anodized receiver and then triple plated barrel, bolt, slide, trigger and mag tube. There were some fully plated 1300 Stainless Marines (with plated receivers) but those are very few and far between. Then Winchester went cheap and made just the coastal marine, which was just a 1300 defender that had a nickel plated barrel and mag tube (yes just nickel).

And now we have the sxp marine, which has a hard chrome barrel and mag tube. Likely not triple plated since they didn’t plate the receiver. Probably just a good ol thick chrome plating. But I can’t confirm that.

Are these coated on the inside of the chamber and barrel? Ie the 590a1 mariner?

Lots of good discussion... I'll add a couple of data items. I have a Browning BPS All Weather, which has a smooth nickel finish on the receiver (inside and out), and the barrel is stainless so no coating.

I had a Remington 7600 Weathermaster, which had the same matte nickel finish as the 870 Marine Magnum --- that finish was also on the inside of the receiver and the outside of the barrel, but not in the barrel itself. A smoothbore shotgun barrel is obviously significantly different from a rifle barrel, so I wouldn't be surprised if the 870 Marine Magnum barrel is coated on the inside.

The all-weather shotgun that I wish I had was the 870 Marine Magnum XCS: https://www.learnaboutguns.com/2008/05/13/remington-870-xcs-marine-magnum-review/

... the exterior of the gun is coated with Remington’s proprietary Black TriNyte corrosion resistant coating. Interior parts are coated with electroless nickel, and the trigger group is plated.

... Nowhere inside or on the barrel, breach, bolt or trigger mechanism is there any indication that this shotgun has ever been outdoors.

Unfortunately, there were issues with that coating. It either held moisture, or the metal was not being prepared properly for treatment. Rust spots would come thru while sitting on a display wall. Remington at the time blamed consumers. Anecdotal.
 
Both the Stainless Marine and Stainless Police were triple plated with chrome being the outer plating. If the police was just nickel, it would have had a slight yellow tinge to it, however it has a blue tinge which is indicative of chrome.

The barrels for the Stainless Marine and Stainless Police WERE made from stainless steel. But it was just the barrels. So the barrels are stainless steel AND triple plated, kinda like having 4 layers of protection. Pretty neat. The receivers are of course aluminum. Winchester advertised the barrels as being stainless steel to accommodate the corrosive effects of gas launcher rounds. The Marine and Police were able to accommodate gas launchers.

Neither of these guns were made with stainless steel alloy... which is a good thing.
"Stainless" does not mean "stainless steel alloy"

Interesting. That's contrary to what I've learned, but I can accept that you may be correct. Are you able to share the source of this info? Specifically where Winchester advertised that they used stainless steel, and that the matte Police is triple plate and not just nickel. Thanks

I'm mostly curious because I actually have both of these in my collection and have a vested interest.
 
The early 1200 Stainless definitely used stainless steel barrels. Corrosion in the bores was an issue and they switched to nickel plating soon after.

I sold my 1200 Police here on CGN many years ago — it had the electrolysis nickel-plated satin finish — but I archived the EE pics:

^ what he said. If you looked at the matte finish one that recently sold on gun post it was stamped stainless
 
Still chapped about missing out on a 'marine coat' Ithaca 37 at auction about 6 years back. Was at the range, bidding kn my phone. Slipped through my fingers.

For sure, you and me both. I love Winchester 1200/1300's and always try to learn more about them.

Here are the ad's I'm referring to: Here's an example of the early "1200 Stainless Marine & Police", an example of the later "Stainless Marine & Police", and then an example where Winchester talks about the gas launcher capability. It would be super cool to get hands on the actual launcher that attached to these 1200's, if it exists lol.

Thank you for this. Genuinely appreciated. I have learned something, and have edited my post to reflect the truth. Very nice advertisements!

That's great information. I'm curious how you know this? That corrosion in the bore was an issue? And what do you mean that they switched to nickel plating soon after? Nickel plating of the bore? Can I read this information somewhere? Thanks
