Is there anything I can read so I can become more knowledgeable in gunz?
Buddy, get your license first, you will learn much there, including how handguns in Canada can only be used to shoot targets, and only at an approved and registered shooting range. You need a piece of paper called an Authorization To Transport (ATT), and this allows you only to move the handgun from your safe to a designated shooting range, where from you must promptly return it to the safe. The entire time in transit your handgun must be in a locked and secure container, accompanied by the ATT, and can only come out at the range. Of course, you also require a restricted firearms license first.
Get caught with your handgun just once off the route to your range, or attempting to shoot it elsewhere than an approved shooting range, and you will likely lose your privelege to own firearms, and also likely lose your ability to own and shoot handguns for life. In all honesty, judgding by your posts, you're simply young and new to things and shouldn't be acquiring any for a very long time until you've matured a good deal. Guns aren't any special power or anything, they can be good recreation however, as long as you use them responsibly and safely. At the moment, you most definitely are approaching them the wrong way, as they do demand respect and reverence for the responsibility of owning and shooting them. You've got a long ways to go, perhaps one day you'll come around and see them more appropriately.
Stopping power for what?
You cannot hunt with Handguns.
.38 special will punch holes in paper just as well as .357
edit; 10 bucks says the OP is a banned user returning to troll.
I referred to the way he posed his question, I didn't say there's no place for a .357, or .44 Magnum etc. I shoot a 10mm Auto, a .40 S&W punches the exact same holes in the same target, but I prefer shooting the more powerful 10mm for the challenge. There's every reason for a law abiding target shooter to own any caliber of handgun that interests him/her, but not when "stopping power" and armour piercing rounds info is being requested contemporaneously.
