I've got one of these and use it as cheap practice gun for my 9mm.
Whilst you might be able to shoot this pistol in ISSF, unless you're an incredible shot or damn lucky, they aren't designed for this type of shooting and your scorinb won't be good. I've seen this 1000 times. People buy a toy and find that its useless in one match, but, a gem in another.
I always say to newbie club members "buy a precision .22 if you like 1 handed matches (ISSF etc) or buy a decent semi auto or revolver for other matches."
As Brett pointed out, in NSW, we have ridiculous laws concerning what you can own when you start out (can't have both CF & a RF).
If you enjoy the one handed matches, look at the Walther precision pistols. They aren't cheap (because they are excellent quality) and you'll shoot reasonably well. Use European ammo in European guns (SK match is a favorite of mine).
You'll love pistols. Best fun you can have with your clothes on.
