I shot for groups at 50 yards open sights. About 1 1/2 inches or so with all ammo. My eyes aren’t the best.
The pistol was reliable and all brass landed about 4 o’clock. This is a very cool little truck type of gun. You can put the barrel on and be ready for action in about 3 seconds. 2 latches is all you have to push together. I took the barrel off a few times and put it back on and it returned to original zero.
