The Discreet Carry Concepts clips are made of spring steel and are an excellent choice if you're concerned about durability of the clips, or want to reduce the profile. They have the added advantage of grabbing clothing, enabling you to wear the holster without a belt, as long as your pants are capable of holding the weight. Developed by professionals in the industry who not only carry guns daily, but are required to regularly employ violence all along the spectrum of violence, these clips have been tested rigorously and passed with flying colors. The Monoblock is a perfect replacement for the traditional FOMI clip, utilizing the same attachment points. 2.73" OAL Fits over belts up to 1.5" (2) .220"H x .300"W horizontal slotted mounting holes will work with spacing that is .860" - 1.15" on center.
