Some observations:

I may be statistically more likely to be struck by lightning then confronted by an armed attacker, but I'm not going to golf during a thundershower. What I mean is that I'm going to be prepared for the danger.

I didn't know that you could fire 9mm in a .357. I know that it is the same diameter, but the rim is different. If someone can show me a pic of the half moon thingy, thanks.

As to the springs, Dave's advice is what I've always heard. But now some of you are telling me what I want to hear, that it is okay to leave a mag loaded. You're assuaging some of my guilt for abusing my tools. But I don't like to accept advice that is what I want to believe. Sceptic at heart.

As to the OP, what was your question again?

Here's how they work,

Nope, 50 people hit by lightning each year in the US, 1.5 MILLION victims of violent crime.... you are far more likely to be threatened by a criminal than mother nature.

1/. Install motion sensors

2/. Change the alarm siren to play the noise of a pump action loading

Calling CRAP!

Nothing but respect for you man, but I have to correct a common misconception.

Springs degrade with multiple compressions/de-compressions.

You can store a loaded magazine with no more ill-effects than an unloaded magazine.

It's basic physics.


In fact, the most dangerous thing that can happen to a loaded magazine over time is the spreading/failing of the feed/magazine lips over long periods of time.

Load them and store them friends, won't hurt a thing. I don't care what the starches in TRADOC hand down...

depends on quality, but compressed springs can set a bit. do you recall shattennjaggeresses truck springs? they failed under a constant load, not from compression cycles.

 

[Jonathan Hanson]

Springs fail when they have been flexed past their yield point. Think of the valve springs in your engine, which can experience a quarter billion cycles over their life, and can often be reinstalled after a valve job. They survive that because they cycle within the limits of their design parameters. Suspension springs sag when they have either repeatedly or for a single protracted instance exceeded those parameters, and molecular bonds start shearing. A properly made spring left compressed within its design length will suffer no fatigue.

Back to topic, again.

I have several Glock magazines that have never stored filled to the brim for 15years, emptied one round at a time at the range. Even then, they are refilled and left to sit for another several months. I've never had a single malfunction.

Rather than debate the theory and physics of springs or parrot back something they heard, has anyone here ever had a magazine failure related to long term storage while filled? Anyone? Bueller? Bueller?

 

[Jonathan Hanson]

I'm positive we could collect a hundred anecdotes from both sides, but they would be just that - anecdotes. Without metallurgical analysis of the spring in question, there's no way to determine why it failed or didn't fail after long-term storage, or indeed if an entirely unrelated problem was the cause - corrosion, bent feed lips, bad follower, etc. etc. etc.

Anecdotally, I've personally heard many more stories of long-term storage having no ill effects. In such cases as Dave described with the Beretta, it seems clear to me that another factor such as poor quality control was the cause of repeated documented failures in one type of weapon.

From what I can gather, for the casual or even frequent shooter, there's little difference in results whether you leave your magazines loaded or constantly cycle through them. In either case a quality magazine spring should be able to handle the stress.

I totally agree on all counts.

It seems to me that LEO's in particular load up their magazine and keep them that way for years on end, yet need them all to work flawlessly at a moment's notice. I would think that if keeping magazines filled up and sitting were so bad, we would have many more first person accounts of failures.

I personally like Tacodoc's "kill zone" theory!

This conversation would be better suited around the campfire about 2 in the morning!

I don't buy into the statistic either, but was using it as an example that I like to be prepared and avoid potential dangers.

with the 2 am buzz on.



the spring issue is quality. the cheap ones set a bit but ive never had a fail to feed because of a spring. i dont know anyone that has. ive used a screwdrivers and pry bars to "open up" a mag a bit to lessen friction.

i also know dudes that store their classic cars on blocks with the wheels off, swearing it saves the springs... not to sure about that one either.

All these post and only one about the most intimedating sound in the world, the pump gun. I subscribe to the policy of two sets of sharp teeth next to the bed. I do have a pump gun in the closet, but as I grab said shot gun, person x is still dealing with rover 1 and rover 2. I have a number of side arms, but the truth of the matter is when adrenaline kicks in, (not being trained militarily or profesionally) these situations take aim out of the picture. I can rack a round into the pump gun letting everyone in the house (invited or not) know my intent. 99% effective, say no more, threat leaves. If threat decides to stay, the 00 buck is going to cut anything in that range in half. No aim, no probelmo. Just point and pull and rack round 2 or more. I have no desire to hurt anyone in this world or the next. But I'd rather be on trail for thier murder insted of having it the other way.

Hoping that it doesn't go int a kids room, or your neighbors house. I use #7 so it will not go through as much stuff before it stops.
