Ammo left in mags..

[likeitfast55]

Whenever you see a gun in my house ---- its loaded. Only the guns in the safe are not.
This is what I have taught my boys from day 1. Unloaded gun = worthless.
I have a mix of wheel guns and glocks scattered all over the house. Basically a gun in every room.
Next to bed is 870 tactical 18 1/2" 7 shot 00 buck 3"mag.

Filling a 30 rd magazine for an extended period of time can weaken the spring, the most I would keep in them would be 28. Now if you want to leave these for years then I'd say no more than 25.

Do you really think by putting less ammo in a 30 round clip that it preserves the mag's ability to push the ammo upward for chamber contact into battery?

and that by 2 less bullets?

Just the spring's integrity... long term.

Several years back some of the Ruger semi-autos reportedly had issues with magazines coming apart at the metal seams when left fully loaded for long periods.

and enjoy tearing up your thumbs needlessly lol

I'm a puss and use an UpLULA.

I haven't conducted a study about it or anything, lol, but fully compressing a spring over a long period of time does seem like it would weaken it.

I always loaded my mags with 28 while I was in a combat zone and they always worked when I needed them to! Just saying

See, though. A spring in a magazine is not fully compressed, unless you start stacking more rounds than what it's rated for (as I said above, putting 13 rounds in a 12 round magazine). There's a "blank" space the magazine that the spring compresses in to. As long as the spring isn't pushed beyond it's elastic limit (ergo, overloaded magazine), it'll last nearly indefinitely.

That reminds me of the first time I went to my in-laws' house. I was opening some drawers looking for a spoon in the kitchen and my MIL asked me what I needed but had kind of a strange look on her face. Turns out there are loaded guns everywhere in all the rooms - drawers in the kitchen, hidden in towels in the bathroom, hidden in the couches and chairs, etc.
Dad told me later that he isn't very fast and too old to fight with this hands so he's ready anytime if somebody comes in the house.

Springs weaken from use due to work-hardening, not from being under compression.

I know quite a few people who know giant amounts about firearms (gun smiths, instructors, competitors), but still refer to all mags as clips. So I will have to disagree on the knowledge part of it, but I do understand that it makes someone look a little silly.

That means, don't listen to them! They are all show and no know!

Definitely never been able to load 31 rounds in a 30 round magazine haha

That's not as telling as if you'd loaded them with 30 or 31 and they did or didn't always work when you needed them to.

[Bassics]

I remember an army field manual for the M16 that specifically stated to load 28 rounds in a 30 round magazine. That was from the 70s though.

[CJ]

Honestly I don't think a fully loaded mag is going to affect the spring or pressure to have any bearing on reliability.

I don't see how a properly designed follower would even allow this.

Once you bottom out that is it, unless you somehow are able to squeeze in one that stresses thelips, in which case you probably will have at least one FTF.
