I'm not sure you understood the intent of his post. He's not necessarily saying don't buy the gun. He's simply saying do not hide it from the wife, or in any way sneak the gun in.
In my case, my wife and I have an understanding. IF I ask before spending the money, and she says no, I cant have it. So, if i really really cant live without it, AND we have the discretionary funds to spend I simply buy it and tell her afterward. She might be mad, but she just adds that amount to what "I owe her". To date she has only called in the I owe her on one occasion. So i still owe her about a bazillion dollars...
