I am agreement with 459 on all counts.
Rent?... I'm alittle confused at this point. Are you allowed to purchase and own guns and since you have to qualify with a gun
Lets say that you need a 200 to pass when I qualify with my work
I am wondering why you don't practice (rent) the gun that will be issued to you. And if it's the .40, then stick with that and practice as much as you can.
I am ashamed to admit that I get confused easily, but I'm trying to make sense of the post so that maybe we can help to pinpoint the knowledge that you need the most.
