I don't practice anything less than 7 yrs.
I practice double shot and rapid fire at 7 yards.
Standard practice is about 15 yards with 1-2 second delays ( to find may mark again )
I almost always push it out to 25 for the last clip or two before leaving the range but it's much slower and steadie,d fire.
I don't try and slow down to the point that I hit dead on accuracy, as for combat shooting I am content with hitting a 4" group at any of the above distances depending on speed of fire. In a self defense situation , quick fire in a 4" Diameter will be enough to save me or my family.
