Best way to install 1 1/2" pine flooring

I purchased some 1 1/2" x 4" x randon lengths tongue and groove pine flooring to do a 524 sq foot room. The room is over a crawl space with floor joist 16" OC and a 3/4 plywood subfloor.
It appears that most flooring nailers are designed to nail up to 33/32" thick T&G. I have not found a flooring nailer that says it will do 1 1/2". Has anyone done this before? What would be the best way to fasten the flooring?
