There is always going to be a debate with any tactical or firearm accessory.   What is it being used for and is it up to the task at hand.   A concealment holster might not be a $180 leather shoulder rig, it coule be something as simple as $12 pocket holster.    There are tactical holsters that will secure your pistol while your running through the mud and training in a Carbine Course, or you can have a IWB holster for your everyday CCW.

Another thing to think about having in your box of holsters is a simple range holster.   If you are at a gun club and  planning on doing some serious range blasting, you might want to consider a range holster.   A range holster is usually something that you can wear outside your belt which is a clip on our paddle style.    Whenever some of my friends and I are going to be pulling an all day range trip, we’re usually carrying a full size handgun and IWB is not a comfortable carry option.  Fobus Holsters are in the $20 range and if you’re wearing a good belt, you won’t notice the weight of a full size gun like a Beretta 92 or Glock 17.   It’ll make carrying and practicing much easier than constantly picking your gun off a table.
