| I was wondering how long a Mossberg 590 (9-shot) magazine spring should function reliably when stored compressed (loaded). FYI, I load only 5 rounds in the magazine and nine at ready on the sling. Should I replace the spring every couple years? What is the standard practice for LEO's pump guns that, I assume, are kept loaded in their cars? [shotgun] |

I checked the Wolff gun springs website. It appears that they sell a generic spring that you cut to length. I was hoping to find a specific replacement. I did find the Mossberg OEM spring at Brownells for about $7.50. I suppose that I will continue to keep five in the magazine and replace the spring yearly, unless I can find some dependable data concerning spring life. It's a cheap and easy PM. |
| I think you should practice with it alot and replace the spring when it begins to fail to feed reliably. Loading the mag tube to its full capacity won't wear out the spring. Springs are worn by many compression and decompression cycles over a long period of time, NOT by constant compression. If this is a LEO weapon, I'll assume it's being loaded and unloaded on a daily basis. That being the case, the spring will malfunction sooner rather than later and I would replace it with a quality Wolff spring. At any rate, don't load it halfway, load it up to the max. HTH |
