I just purchased a Taurus PT111 Millenium Pro 9mm. I know, it's not a great "competition" pistol, but I am just starting out, and it's what I will carry for self-defense as soon as my CCW permit comes in.
I just really want to get to be a better shot with my self-defense weapon first, and have fun shooting. I go to my local indoor range at least once a week, but I'm looking for something a bit more challenging.
Once I get more involved in the sport, I plan to get a 5" semi-automatic. Of course, I plan to shoot in the "Production" class. The nearest USPSA club is about an hour away, and they have matches the first Sunday of every month, so I plan to head up to at least watch the match next month.
