Welcome to the forum, thats a nice looking early shipment (1938) Brazilian, smooth grips are proper for the revolver as are the lanyard ring, it should have a serrated trigger as well. I like them and have one that I've been fooling around with, its one of my favorite shooters. Enjoy it, they are very pleasant to shoot. You can use .45ACP cartridges and poke the empties out with a pencil, or use moon clips and eject them wholesale, also and my personal favorite is the .45 Auto Rim which allows you to eject the empties just like any normal revolver.
