I always laugh when people say 9mm isn't good enough.
For home defense I only keep one mag loaded less than Max capacity. No need to wear out the other ones.
My work mags on the other hand are loaded to the brim 24/7/365. I hope they actually feed bullets if I ever need them too. Although that's not such an issue with belt fed. But our 249's arnt greased up so they will jam fest reguardless.
