I did this one a few hours ago, 5 rounds at 45 feet (15 yards) using an Isosceles stance off hand.
The whole target is 6 inches in circumference, the inner circle is 3 inches and the square is 1 inch. All 5 rounds did a 2 1/2 inch group center to center but if you don't count the 1 o'clock flyer then 4 of the rounds did a 1 inch center to center group. Pretty good w/o a rest IMO especially for a nearly stock Glock (Sights, smooth out trigger components, Tungsten Guide Rod and 15# ISMI Guide Rod Spring)









Looks like they make a nice product though
