I would like to leave both clips loaded so I can quickly arm my M9, however I'm wondering if this will sack the magazine spring over time. What's the best practice here?

I have always wondered that too. I leave both of my magazines full. Has anyone every seen a speed loader available like the M16 has?

Generally
Leaving a magazine loaded has no effect on springs. It's when you constantly load and unload a magazine that springs get fatigued. Leaving the magazine either fully loaded (spring compressed) or unloaded (uncompressed) has no effect.

springs are designed to provide energy. when they are at rest they are fine.

yes generally, but if you keep something compressed for extremely long periods of time its form will deteriorate.

my advice is to load one mag (why do you need two unless you're leo) and to switch them occasionally. i try to do it monthly.

Never happen unless the spring was defective in material, manufacture, or someone's modified it. This article says it all.
