Carries both firearm and magazine OWB in 1 compact design. You get to choose front and back kydex color as well as the finishing washer color. Don't be scared to get creative. THE FIREARMS LISTED WITH RAIL ATTACHMENTS ARE NOT GUARANTEED TO WORK. IT IS YOUR RESPONSIBILITY TO MAKE SURE THE COMBO YOU CHOOSE WILL ACTUALLY WORK WITH THE FIREARM YOU ARE CHOOSING. IF IT'S A COMBINATION YOU CURRENTLY ARE RUNNING, THEN OBVIOUSLY IT WORKS.
