All - how long can you keep ammo stored in a magazine? I'm debating the issue of a revolver vs. an autoloader - it seems that a selling point for the revolver is that it can be kept loaded without any parts going bad. With an autoloader - will the spring in the magazine deform or the bullets poorly load if the magazine is kept loaded for extended periods of time? This is also tied to the Glock 21 posting I just put up - it's either that or a S&W 686
