The slider is an Outside the waist band holster. A good range holster or I wear one under a shirt concealing the firearm just fine.  It is more or a flat back holster. That is that the molding is mostly on the front side of the holster.  The belt loops are not visible from the front, they are more of a belt "tunnel".  It has the least retention of all my holsters, yet I have crawled around, changing my oil on my truck without any issues, but It does need mentioning. 

Slider starts at $50.00
