Well you are in Canada, so as far as take down power is concerned, unless you have some pretty mean paper targets with attitide, that shouldnt be a concern

. Seriously though, there are many opinions on both calibers and this forum will certainly prove that. The 40SW is a great caliber but cheap it isnt, unless you are reloading(and even then, components are not always readily available). For a newbie, the 9mm is an excellent choice as it serves both the new shooter as well as the very experienced shooter. Depending on how you plan on using the weapon, you need to do some research. Weapon choice will also be anything but easy are there are pros and cons with any pistol and opinions are varied and many

. If you have access to a range or a retailer, you would be best to go and look/feel at the choices out there and let your personal preference make the decision, not heresay from somebody else

. Every shooter has a different hand and grip styles are numerous. Find one that suits you.
Most importantly, don't rush into this. Do some research and get opinions. Remember that they are just that, opinions and ultimately the decision is yours.
Depending on your experience level, the possibility that neither is a good choice for a first time shooter exists. Don't be influenced by dollars. Granted there are some excellent low cost choices out there, but cheap doesnt always mean good. Be aware. And just because it costs $1000 and is an excellent overall weapon doesnt mean that it is right for you. You can always upgrade once you learn the mechanics, but an unreliable cheap gun is the fastest way to lose interest through frustration.
Okay, I have spewed enough. Good luck with your pursuit and take your time.
