Congrats...I've also got an early issue Brazilian model, it was my first revolver chambered in .45acp. I immediately found a new pistol to shoot. If you like to mess around with cast bullets you can have alot of fun with these little .45's. I've become so addicted to shooting mine that it sent me off on a quest for a serious revolver in the same caliber and ended up with a terrific pre-number model of 1955 from a forum member. Find the grips that suit you best and enjoy shooting it. My hand completely swallows magnas, I've got them on an Outdoorsman and even with the T-grip its not comfortable to shoot, if it ain't comfortable your not going to shoot it as good as you could if it was. I had a pair of rosewood target stocks intended for the Outdoorsman, they ended up on the Brazilian and thats the end of that problem. If you don't already know what fits your hand, go to a local gunshop and try a few on, you can usually find a bit of everything if you look around. For me its always been N-frame square butt presentation target stocks, I even had John whip me a pair for a round butt framed 629...perfection. I don't care for rubber grips, I ain't saying they don't work....just don't care for them. Find what fits your hand and feels good to you, forget the rest, its a shooter...unless your going to use it in a WWII reenactment and dress up like Juan Valdez.
You will find that it will shoot factory hardball 230 gr bullets real well, thats what it was basically designed to do. They have real shallow rifling. I use a 200 grn SWC with Lyman #2 alloy over 4.5grn of Bullseye, I'm also experimenting with Titegroup and 185 grn Hornady XTP's. The trick is to find the right load that shoots to your chosen point of aim. I'm finding I need to beef up my cast bullet load or maybe switch to a heavier bullet...thats half the fun of a new pistol is figuring out what it likes.
I have an old beater and you are quite right about the shallow rifling, probably the most shallow I have seen. Mine shoots low and I could probably get it to come up some with heavier slugs, but I just hold a little front sight in the rear notch and it hits well.
