Always Carry, Never Tell
Now you can carry 2 extra magazines either way you choose, outside the waist on your belt or neatly tucked away inside your waist. Remember if you are planning to wear this inside your waistband along with an IWB holster, that is going to take up a lot of room and you may have to buy pants as much as 2 sizes larger than normal. That is the main reason I build these with the belt slots already in them.
