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.
