Money, or the lack there of, is my biggest factor.
My wife isn't an issue, and is all for me buying firearms, especially if they are "pretty". She was raised round firearms, enjoys target shooting (used to go out with her dad and put a couple thousand rounds through his M-16 and MP-5 when he was senior swat officer), knows that I enjoy them, and likes the meat I bring home with them.
But, even with no car payments............. the mortgage, utilities, food, gas, etc., 16 month old daughter, and a 3 month old son who just got home after 95 days in the NICU.............finances are a bit tight right now.
Our income has been cut in half with the wife staying home to look after our son for the next few months, so even a $25 box of bullets or pound of powder is on the back burner until the finances get straightened out, and a gun purchase of several hundred dollars is a pipe dream.
I have everything I need for target shooting and hunting, so new firearms would be a "want", not a "need", and I still need to pick up a bigger safe anyway since I can't fit anymore in the current one, so a little pause in the purchasing won't really hurt anything.
