Okay, so you have a 5-month old.
One of the greatest qualities gun owners have is a keen sense of justification, okay? We already know that any revolver you buy now will only go up in value, so as an investment it's pretty good. Instead of a useless paper savings bond (which is one government note respresenting another), you can have something of worth for the child later in life, be it male or female.
Now a GP-100 is well under a grand, so this really isn't a problem, right? You just have to get creative. The best way to do this is to maintain secrecy. Wives are the greatest single inhibition to men doing what they know is right, like supporting the gun industry at a time when our pinko liberal politicians are trying to put them out of business.
A few hundred dollars of debt isn't going to kill anyone, so think credit card. Get one that has a zero percent interest until next year, okay? Once that's done, you simply buy the gun on credit.
Anyone who can't pay off a few hundred dollars in a year shouldn't have any guns. Now, when you shop, buy all the cheap brands. Sure you may have to use el cheapo toilet paper for a year, but you'll just learn to appreciate the good stuff afterwards, and you'll have a GP-100. Start collecting spare change in a jar. Steal money out of your wife's purse (you're using the gun to defend her for heaven's sake!). Hit your parents up for money -- that's a great way. And (this is very important): cheap out on your wife's birthday and anniversary gifts. Women don't put price tags on gifts; it's the thought that counts. Finally, when you have a few moments to spare during lunch and after work, go to an intersection and clean windshields. Wear old clothes.
You'll become more creative as you start cutting corners. AND you'll have a GP-100.
Believe me, it ain't that hard. In fact, I think I'll go out and get one. Or better, let's all go out and get one, then we'll have a contest where the first one who pays off the debt wins a box of ammo.
Now start thinking positively!
