I will not explain all the circumstances but here it is. I have heard over the years about how some people are concerned about spring life, ie how/if/when the springs in the magazines will go soft or how long the recoil springs in an auto loader will last. Here's a little story that might clear up a couple of concerns. My Ruger KP89 went to jail about six years ago. It was a piece of evidence. I was not involved in anyway, but under some rather unusual circumstances, it was. I just got it back about two weeks ago. Now for the real story. When I picked up my beloved Ruger, it was in a box with the slide locked back with a plastic electrical tie through the ejection port and magazine well. The magazine that was in the gun at the time of confiscation was in the box as well with all 15 rounds in it! Here is what effect it had on the gun and magazine. NONE! The only thing wrong with the gun was that it had been sitting so long all the lube (always light on my guns) had disappeared and the slide would catch slightly and not allow the slide to fully rack forward if you did it slow. It would even lock/stick back and only come forward very, very slowly if you let it go gradually. After a thorough cleaning with CLP it was perfect. The magazine still functions flawlessly as well. So any concerns about unloading and or rotating mags. to keep the springs in shape are at least with this firearm, a moot point. I knew guys when I was a professional, that would regularly take their mags. apart and stretch the springs to make them stronger. I knew then as I do now that it actually weakens the springs. So if you are into this practice, stop it! This little story ought to quell all fears of magazine spring failure. Toodles.

I don't worry about it, but I do on occasion rotate my mags. It does not cost or hurt nothing. I agree that it is not worth worrying about. I have heard that it is not a good idea to have magazine springs in home defense shotguns fully compressed though. Most "experts" say to at least download by one shell.

I was always taught to unload/reload mags periodically-I felt silly because it just didn't make sense that a few minutes' relaxation would make a difference to a mechanical thing...thanks for the proof that we don't have to-though it doesn't hurt to. KP97DC----only TWO loaded mags? The county don't drive that fast...better load 6 or 8!!!! Those field rats travel in herds. Tim, I've heard that about shotguns-even the 870-but I don't know-never had a feed problem. I read somewhere where the flex/unflex is the weakening factor-not being left compressed-I always lube my spring tube lightly and don't worry about it.

I think the shotgun thing might be a myth also. The local P.D. has (had?) Winchester pumps in all the cars and they were always loaded except at qualification. They all got a box of 8's shot thru them and then were reloaded with 00 buck. I know for a fact that they were constantly loaded for 8 years and I don't know of anyone who had problems with them.

Ain't nothin' good like good news!! Thanks, guys!
My uncle brought back a Browning Hi-Power from WW2, loaded it with a full magazine and put it in a box in the closet in 1945. There it sat untill the early seventies when he told me about it. I, having been in smithin' for several years had also heard many rumors about "spring set" and curiosity got the better of me. I gave the gun a light cleaning except for the magazine, and took it out to shoot. Every single cartridge fed and fired in that magazine perfectly. I was surprised and it "changed" my way of thinking about springs. Although I have seen some springs take a bad set, the opposite has been the norm. If springs are well made and tempered, they usually last a very long time, even under stress..................Dick

About once a year I remove the cartridges from my .45 mags, wipe them down and inspect, lube the mags, then reload and make ready for use. About eleven years doing this and no lost tension or feed problems. I do take it out a couple times a year and feed a couple of mags of reloads through it, just to give me the excuse to clean it.
I have a 32acp PPK that was left with loaded mags in my Mom's attic for over twenty years before I snagged it and it also functions perfectly.
