Which Servo Should I Choose For My Nerf Gun?

I wanted to build a servo automated nerf gun ,however i am not sure what type of servo i should choose and how much torque i will require.The gun i want to trigger is a semi automatic nerf barricade rv-10 .Should i buy the small 9g hobby servos' or will my need be satisfied y the larger ones which provide torque.I am not using anything to amplify the pull of the trigger by the servo and i am connecting the servo horn directly to the trigger using a small metallic wire like piece .Please help me chose a servo. 

Torque requirements are dictated by the desired speed of response, and the moment of inertia of your load. Until you have a handle on that, you can't specify the servo properly. You're left with "try it and see"

But you got lots more interesting related ibles on the right side of this page.

I particularly like the

modify a 270° swing servo for continuous rotation.
