Stock up on additional magazines whenever you can, as more mags are always helpful. For training, tactical, or recreational use, having multiple magazines is tremendously helpful. Having dozens of pre-loaded magazines is even better, as this arrangement allows you to spend all your time shooting and dumping magazines, instead of tediously filling them up one round at a time at the range.
