Can I use an air-actuated framing nailer gun to nail parallel 2x4s

I have a home business, and one of the tasks is to screw 2x4s together
to make one thick post. I spread glue on the 3.5" wide faces, then
clamp them together before fastening.

Instead of driving deck screws for fastening, I am curious if I can
use a pneumatic framing nailer.

Would I split the wood?

Why use a nail gun? Just do what this guy does...
