Zhurdan is right on the money with the cant.
A neutral cant is more conducive to the ergonomics of a draw stroke. The disadvantage is that it causes the but of the gun to “print” on the back of the covering garment. By canting the holster along the line of the body it helps reduce printing.
The same is true regarding how close the gun is to your body. IWB holsters work well as they have a belt pressing the gun into the body. It is a little slower to draw the gun than a holster worn on the belt, but it prints less.
