He asked what was most durable, SS is going to be more durable than any plastic made.Magpul still has loaded gen 1 prototypes of their mags and they run fine.
Lots of bashing polymer for mostly poor reasons. The argument about knives and rifle barrels makes very little sense because the reason those aren't plastic is mostly due to the increased rigidity you get with steel (also keep in mind these mags are usually aluminum not steel but there are steel ones out there), not so much the strength of the material.
For sake of clarity, I'll be referring to three types of mags.
Metal: Okay Ind., Brownells, USGI aluminum mags, etc.
Hybrid: Lancer mags with metal feed lips and poly body.
Polymer: Magpul, Troy, etc.
The problem with metal mags is that they are rigid, and when bent, they're toast. Run them over with a truck, they might be fine but if there's a rock in an unfortunate place, it's toast. They're also not quite as impact resistant as a polymer mag. That being said, metal mags are still durable as hell and I run them because they work very well. If you get surplus USGI mags, you may have to change the spring out as they've been used and abused, but that's not necessarily specific to metal mags.
Pmags have a little give to them. If you run them over, they'll bend and return to their original shape. Drop them, there's a little better impact resistance. The only weak spot is on the spine closest to the feed lips. Drop a loaded mag just right and you can crack the spine. The other problem I've had with Pmags is sometimes they'll swell a little bit and won't drop free.
Hybrid mags like the lancers combine all these things into one and add a nice useful touch with their translucent polymer. The spine is reinforced with a metal strap, most of the body is a polymer so crush and impact resistance are there, and the chances of sticking in the magwell are reduced because half of the material that fits in the magwell is metal and I think lancer has their poly figured out a little better than magpul.
Overall, if you stay away from pro mag and other shit brands, you'll be fine. Magpul, Lancer, and USGI mags have no issue with long term storage while loaded, and are very durable.
What firearm?Which mags are more durable stainless or polymer?
Guess you've missed the demonstrations of PMags getting run over by a Suburban and still functioning despite being cracked in the spine. Try that with an aluminum or steel mag and let me know how it works out for you. Even the vaunted, $70 a piece steel HK SA80A2/416 mag fails that test. BTW, PMags have been tested in cold weather and worked fine. I've jumped out of airplanes with them and they didn't spontaneously explode either. It's not like there's not thousands of them in service with DOD and allied militaries or anything. And before you go "Lowest bidder!"-they cost the government more per magazine than aluminum mags. Gen 3 PMag and the latest aluminum coyote brown/FDE mag with a blue follower are the only mags actually designed for, and supposed to be used with M855A1. I get the aversion to polymer, but PMags have been proven many times over.He asked what was most durable, SS is going to be more durable than any plastic made.
There is also the issue with plastics in cold weather, i dont know of any SS that gets britle when it is extreamly cold.
I have SS, aluminum and polymer magazines and like them all but prefer the SS and aluminum.
If i loose a magazine do to damage i would prefer it not be the most expensive polymer ones that are also heavier than the GI mags.
I haven't had a single issue due to cold weather with any of my polymer mags, and they've been dropped on hard surfaces plenty in below freezing and sometimes sub zero temps. Thats not to say they don't get more brittle in the cold, but I haven't found that it becomes an issue in WI winters.He asked what was most durable, SS is going to be more durable than any plastic made.

No need to mess with dust covers when you have one in the rifle ready for someone breaking in the door. Just sayin...I keep lancers loaded for HD because of the metal feed lips I don't have to mess with a mag cover with someone breaking in the door.
All other uses I use PMAG M3 because its combat proven and their cheap.
Exactly what I want in a "stash" mag.

Army Test: PMAG Outperformed Enhanced GI Magazine Fielded in 2016
The U.S. Army Aberdeen Test Center's 2015 Final Report shows the PMAG Gen M3 performed better than nine other magazines.www.military.com
Yeah, having lived through the Clinton AWB years, I started buying in earnest as soon as it expired. I used to watch CDNNsports for clearance mags. I paid $4 - $10 per for most of mine.The truth of the matter is that ar mags, regardless of build material, are all sufficiently durable to gather dust on top of you hastily acquired pandemic hoard. Admit it, 95% of the mags you buy will sit in the back of the closet, and most of that will be factory sealed when the mid-terms roll around. Hell, I have unopened mags that were bought after Sandyhook...
Thats a steal and they are gone....
There was 23 when I posted it. I knew after I posted they would be gone fastThats a steal and they are gone....
Paying for the Colt name? PA haven’t historically been guilty of opportunistic pricing...Then you have Primary arms, selling them for $40 and being sold oout.
Colt USGI 5.56 NATO Magazine - Black - 30 Round (primaryarms.com)
Well, since the OP didn't specify what rifle, but has numerous posts about mag release issues in a home-built large-frame, I will address that rifle.Which mags are more durable stainless or polymer?
Bought 10 of them immediately after seeing that post. @TxWelder35 thx for the heads upThats a steal and they are gone....
‘Twas a good deal. I almost bought 10 also but I had just spend couple Hundo on mags earlier in the day from gun mag warehouse.Bought 10 of them immediately after seeing that post. @TxWelder35 thx for the heads up
