As a newcomer to handguns in the past year, I have read several articles about not leaving a magazine loaded over a period of time due to stretching of the spring. Is this really the case? How long is a " long time? If I don't use the mag for, say, one month and then use it on the range will I have a problem? My usual range/carry guns are a .380 and a 9mm. Any help on this topic will be greatly appreciated before I get into a really bad habit where mags are concerned.
Many thanks. jclaudek
This page should help since most magazine springs ARE Wolff gun springs these days.
Frequently Asked Questions
The correct term is spring fatigue. Many older magazines were bad for this after being loaded for long periods of time. They would take a "set" and fail to push the rounds up with enough force and cause feeding issues.
The springs of modern magazines are made of better quality steel. Those made by reputable manafacteres will last a long time compressed. My duty mags have been loaded for over 6 years and still work fine.
A good thing to do, and it may make you feel better, (it does me) is to leave your mags minus 1 or 2 rounds, as I feel that this extends the life of your mags.
Also, companies like Wolf and others make high quality replacement springs that you can purchase and have to replace your old ones as a preventitive measure if you desire.
Having said all of that, I wouldnt worry to much about it.
First of all, welcome to the forum. I was born and raised right outside of Cincinnati, and still call the area home.
The thing that wears out magazine springs, is excessive cycles or expansion and compression. So if you are constantly loading and unloading it. If it remains in one spot, loaded or unleaded, it doesn't really matter. I tend to just keep my magazines loaded, I have fired some that have been loaded for more than a year, and not had a problem with them.
Thanks for that--- very helpful!
When you disassemble and clean your magazines VERY CAREFULLY look over your magazine springs.
Any magazine springs that show any signs of rust or pitting should be promptly replaced.
Any nicks or pitting that compromise the surface integrity of a wire spring will create a weak spot when the spring is compressed.
The spring will fatigue or fail in that spot first.
