You can also just unequip the gun before firing, but that breaks immersion. If I recall correctly, the XM16 and AK47 became essentially unusable because a soft press aims and hard press fires. But on the Vita the gun always instantly fires if you try to aim it.
The vol1 collection gets around this by using the left bumper. Hold the bumper when you wanna let go of your gun without shooting.
It’s not ideal, but it works well enough.
