The search was: "walther p-22 for concealed carry."
I suppose you could. It's small, light, thin, and should be very easy to conceal. But it's a .22.
The only reason I would carry a .22 for self defense is if all my other guns were stolen and I was on my way to the gun store to buy a new .357 magnum.
Also, I have a question. Is there a good reason to remove a magazine disconnect? Because I got a search hit for that too, regarding the Ruger SR9. This seems to me to be something that shouldn't be done, but maybe I'm wrong.
