How Long Can You Leave Magazines Loaded?

Published on August 17, 2022
Duration: 8:04

Leaving magazines loaded for extended periods does not significantly degrade spring performance due to static compression; spring wear primarily occurs through cycling. Regular maintenance, such as cleaning every 5-6 months, is crucial to prevent feeding issues caused by debris. Polymer magazines, like Magpul PMAGs, benefit from dust covers that relieve pressure on feed lips, preventing deformation over time.

Quick Summary

Leaving firearm magazines loaded does not significantly harm the spring due to static compression; wear occurs mainly from cycling. Regular cleaning every 5-6 months is vital to prevent malfunctions caused by debris, and dust covers on polymer mags protect feed lips.

Frequently Asked Questions

Can leaving a firearm magazine loaded damage the spring?

No, leaving a magazine loaded for extended periods does not significantly damage the spring. Springs wear out primarily from the repeated action of compression and decompression during cycling, not from static compression.

How often should I clean my loaded firearm magazines?

It's recommended to clean your loaded magazines every 5-6 months. This helps remove lint, dust, and debris that can cause feeding issues, regardless of the spring's compression state.

Do dust covers on polymer magazines serve a purpose when loaded?

Yes, dust covers on polymer magazines like Magpul PMAGs are designed to relieve pressure on the feed lips. This prevents polymer creep or deformation over time from the constant load of ammunition.

What causes firearm magazines to fail?

Magazine failures are often caused by dirt, debris, or lint accumulation inside the magazine, which impedes smooth feeding. Worn-out springs or damaged feed lips can also contribute to malfunctions.
