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

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?

Others have answered the nail question.

I will add a bit.

The trick to nailing two (or more) 2X members together so you have a
straight member is to eyeball them and then lay them so the curve is
opposite. Start nailing at one end and keep pulling the opposite ends
to make the area being nailed match each other as you proceed. A
helper is nice but not really needed.

It will be easy at the start but grows harder the nearer you approach
the opposite end. The last nail or two may require a clamp to make
the members match.

If you start with two members of approximately equal curviture, the
finshed product will be straight.
