The EX was the first IWB holster to offer an interchangeable belt loop system, an original Milt Sparks Holsters design concept. A holster functions best when  fitted to the belt that will carry the handgun. By ordering additional belt loops you have the versatility 

of using the same holster properly fitted to a variety of belts from 1",  to 1 3/4" in width.

The EX sets the gun deeper in the waistband when compared to our standard Summer Special, and places the metal reinforced mouth directly beneath the belt where it does the most good. Above the mouth of the holster, and between you and the gun, a leather extension provides protection from safeties and keeps you from re-holstering your shirt.
