go .45
Ok, first of all, you rock - men with guns ARE freaking hot, and that's just a fact of nature.
Since your hubby already has a .22, the boys may as well learn on that. Consider it a step up from the bb. You HAVE to remember to teach them: Safety, safety, safety first.
If you want them (and your home) to be equipped for real protection though, you can be sure to stop an intruder with a .45. Any asshead pumped up on adrenaline alone will be able to walk through .22 fire like it was your son's bb gun. And who wants to only be able to compare their arsenal to Hilary's anyway?
Additionally, a straightforward .45 is as manly as handguns get (in my op). 1911's are nice. If you're not sure how he'll like a .45, you can go for a GI model: it's simple, won't blow out your bank account, will blow out *choose your graphic description*. I recommend staying away from plastic guns, especially one that kicks like a .45. The weight from the steel will help the shooter hold the gun steady. Think about that for your boys too. I handle my .45 just fine, and I have nO meat on my arms!
There was a guy out in Florida selling a shorty .45 here on AW not long ago. Maybe check that out?
Oh, and definitely don't get rid of it now. In this market volatility, commodities and tangible goods like guns are likely to retain their value much better than, say, your IRA.
Happy Anniversary and Valentine's Day!
