Here's my opinion...
Before committing to any one firearm or any one shooting sport I recommend you go to TSE (since you're in Airdrie) and try as many different firearms as possible. Find, first of all, what works for you (based on ergonomics, SA, DA or both, parts, services, etc.). After that, determine what kind of activity/sport you want to be part of. Talk to people, go watch IPSC, IDPA matches, etc. There are a variety of different entry level courses you can take in order to become familiarized with the draw stroke, presentation, sight picture, stance, grip, trigger reset, etc. Your goal at this point should be proper technique, and not speed or accuracy (they will come to you with proper training). At this point, you should be able to determine whether you want to sign up for IPSC, IDPA or both. Remember, make sure you have the proper certification for the sport you choose. At this point, you have probably made a decision regarding the firearm; now research your equipment such as holsters, mag pouches, etc. You want to make sure they comply with the sport you've chosen. Practice a lot, but with purpose.
