To steady your aim with the Springfield, or any other gun with a scope equipped, this is an effective trick to help you win the day. Go into Aim Mode. You will note the two crosshair halves on the left. Gently press the R2 button down until the two halves merge, then fire at your target. *Note: This process takes a while. Be wary of grenades thrown at you.
In single player, switch to your pistol. Tap R2 with two fingers one after the other. You'll fire significantly faster, this can only be done with a pistol.
