I know I'm fairly green, but stay with me here for a minute. Most everyone has a mag loaded with personal defense rounds. Other mags are used with target rounds and get emptied and filled semi-regularly. The numbers here dont matter much. But the PD mag, hopefully, never gets used. Are we to just assume it'll work as promised, kept loaded, 5 , 10 years down time road? Is there a common practice out there of unloading it every so often?
