But that's your mortgage, or mine. If you live in a 10 million dollar house your mortgage is much higher than mine or likely yours but I hope that's not the case. When I was 18 I lived in an 8k dollar 50 foot trailer. I wouldn't have (and certainly couldn't have) spent the 2 thousand I voted for back then on a gun.....2k would have bought the car I drove back then 4 times over.
I have an older neighbor (a neighbor here is miles away) who got high 6 figure bonuses for airplane sales. His ferrari costed roughly what my house did. But to him it's not a huge thing. And if he were a shooter, And he may be, idk, I'll bet his upper limit would be staggering to you or I.

When I lived in that 8 thousand dollar trailer I bought a beretta 96. So I'm guessing my limit was about 5-600 bucks. Before that I dual wielded Jennings j22s (not to be cool but for redundancy, surely one would go off). So my limit was about 75 bucks.
