The G2 is the same as the G1 Holster, except it has a cut down "H" front to accommodate Red Dot Optics.
Originally designed for the Department of Energy, the G1 Holster has a tunnel belt loop in a butt forward position. The trailing edge of the holster is slotted for the belt which pulls the gun butt in tight for concealment and enhances stability. The pistols trigger guard is fully enclosed and has a thumb break for maximum security.
