No, I think that's just an optical illusion. It's hard to see because of the depth of focus blurring, but Judy is definitely closer to the camera than the MC's gun. Sonja's arm is nearly full extended whereas the MC's is close to his body so I think her hand is roughly even with his; she should have a clear field of fire. But that's about all she has going for her. Her eyes are nowhere near Judy's sights (even assuming she can see past the MC's gun once it starts jumping), her hand would be in for a beating if his gun needs to eject casings, and even Sonja's muscles would be hard pressed to hold Judy on target with so little leverage.
This is not a sound tactical stance.
