I invest in 22 caliber Military Trainers mainly USA and Isreali. Plus target rifles. Almost all of my 'tickle my fancy' buying is in the past.
I've never asked the wife to buy gun but I'm unusable that I use wheeling and dealing funds for buys and never household funds.
I've lived 51 yrs of marriage by these rules.
If it's legal, moral, I think it's a good decision, and I have the extra funds I probably will do it. Now I'm selling off and banking the funds but I did just pick up a new Isreali Trainer yesterday.
