So I'll be pulling the trigger on my first pistol (figuratively and literally) in the next few weeks. I've decided on the Springfield XD 4" in either 9mm or .40s&w. I can't decide. A close friend of mine has the 9mm and I've shot it extensively and even field stripped it. I love the gun but I can't decide if I want to go for the slightly larger caliber. The only drawbacks I see to the .40 is that bulk ammo is slightly more expensive and it only holds 12 rounds as opposed to 16 in the 9mm. This gun will be heavily used for target shooting and I plan to keep it for a long time. I also plan on keeping it as a home defense gun but it'll probably be a backup to my shotgun.
