Powerfactor show went over GSSF(Glock Shooting Sport Foundation) match. One of he things you can benefit is that (at least some I've been to) there are armorers who will look at your Glock and update the parts if needed. Also, it's a no stress fun shooting game. This is not as extensive as IDPA or USPSA so it's a great start for those who want to get a taste of shooting matches.
