I am looking at getting a pistol it would be my first. I'm starting by deciding what model and then I'll start to consider the caliber. I've mostly looked at the Glocks however I've also has some suggest the springfield XD What does everyone here think? Or do you have any other suggestions. I know that some will suggest what feels best or what I can shoot the tightest groups with. This will surely be very important in the final decision but I need know some good guns to start looking at.
