IPSC and IDPA have their shortcomings, to be sure, but to dismiss either as only a worthless game misses the point. YOU decide what gun to shoot, what holster to wear, whether or not to use cover, etc.
There is NO rule in IPSC that mandates that you MUST use a pure race rig. At least one GrandMaster uses an inside the pants holster,proving it's his skill, not equipment.
Those that smugly put down IPSC/IDPA sometimes say that they "set up their own courses of fire" instead. When questioned, these "courses of fire" are extremely lacking in many ways.
Then there are the people that do NOTHING as an alternative.
Anything that gets Joe Schmuck off the couch and on the range is a good thing !
