Springfield Armory XD Magazines
Q. Why do I need more mags? My pistol already came with two.
A. There are multiple reasons. Front Sight, Gun Site, and many other top training facilities recommend that your defensive pistol should have at lest 4 magazines if not a couple more. This is for one in the gun, two on the hip and one spare. This ensures that you have the ability to carry 3 mags whenever you are carrying.
The other benefit of additional mags is less time spent reloading. The more loaded mags you take with you to the range, the more fun you can have before you have to stop and reload.
