    Exploding Gun Myths

    Now everyone knows that if you leave your pistol or rifle magazines loaded the spring will take a set and the magazine will not work. Doesn't everyone believe that myth?

    Tan't so.

    First lets look at springs and metal. We will start with just metal first. OK you take a piece of metal, Wire will do, and bend it 30 Deg. Now if you put a weight on that wire, 4 oz will do and go back a year later. Will that metal break when you straighten it out.

    No. Why? because you put tension on it and that is all.

    OK now you take the same piece of wire and bend it 30 Deg. and then bend it back straight. Then bend it 30 Deg. and then bend it back straight. Keep that up and what will happen? You know.... the wire will break very soon. Now back to the spring in a pistol or rifle magazine.

    A spring is a piece of wire metal that is bent and then heat treated to give it spring(memory) and if you put a weight (cartridges) on it, bending it, and then leave it there for a year, what will happen? It might be fore-shortened slightly but when the weight is lifted it will go back to it's original size or close to it. Will it immediately break? No. What will make that wire spring break? The same thing that made the piece of wire above break. Bend, Straighten, Bend, Straighten,Bend Straighten, etc. In other words using the magazine and compressing the spring and then releasing the tension again and again and again is what makes springs break or wear out.

    Not just being under tension.

    I appreciate this information.

    I'm pretty new to all of this stuff, but have some magazines that have been filled for about a year. I could definitely see people having filled mags (especially for SUR's like an AR-15) that have been sitting compressed for year after year after year.

    I've spent a lot of spare minutes here and there thinking about how I would start a rotation, cycling a number of mags into "empty" status and then back into service.

    It sounds from this report, that I should just load my mags, set them aside, and spend any energy on making money to buy more mags and ammo. I'd like to hear more thoughts about this "myth."

    Great post.

    I keep two ar15 mags loaded with 27 rounds,a habit from the army days. When my edc gun mags are fully loaded, I chamber a round leaving the mag minus one round. I have not had any spring issues yet.

    Cycles wear out magazine springs. Leaving them loaded is no problem.

    I have bought 1911's that were left in a footlocker since WW2 with loaded magazines and fired them all with no problem.

    Thats good news since I leave my ar and ak mags loaded all the time, funny thing though in the service they would pick 10% of every body armed up in the morning before heading to work to block there ammo, which is to take out all the ammo ( in my case 7 30rd mags i.e. 210 rounds) and put them in a plastic block so they can check the ammo and also they told us it was to temporyily relive tension off the mags! LOL:rolleyes: I think of all that time wasted striping and reloading mags a few times a week!

    sarge is totally correct. unless the magazine is contaminated with water or dirt or whatever it should just be left. the only proper way to unload a clean magazine is one at a time witht he bullets leaving the muzzle of the weapon.

    There WAS a case of a 1911 pistol found with a magazine that had been loaded in the 1920s. Found in the 1990s, IIRC. After sitting for 70 years, the mag was fired. No problems.

    If springs lost their spring just from standing with weight on them, my 1985 F-150 would be sitting on the ground- those springs have been under load since the day the truck was built. You do not go out at night, and jack up the truck to relieve the pressure on the springs, do you?

    Springs fail from being OVER extended, and from cycling (metal fatigue) Think about all the springs that are in a firearm besides the magazine.

    Tell me did they also tell you to clean the mag. body while you were waiting? I'll bet that that was the real reason.

    I've thought about the hammer spring on a 1911...

    I keep both my Colt 3" and Springer 5" cocked and locked at all times. If this "Let the magazine spring rest" lameness was true, then people should be claiming that hammer springs need to rest and should be released on the Sabbath from sundown to sundown.

    Not when doing this before duty every day. we only had about 10 mins or so to do it and there would be quite a few of us, waiting for an armorer to check it, one of the bigger reasons it was done also was there were a few idiots who decided to steal a few rounds from there mags and replace with broken pencils under still exsiting ammo, so it gave the illusion all rounds were there, because before all that the armorer would only press down on the mags at the end of the shift to make sure they were full. But years went by and they said it was still being done for the intention of the mags. Funny thing we never shot that ammo, and we always shot new ammo when we would qualifiy.:rolleyes:
