For the Firearms guys

axio

I do. I have the full size USP in .45 caliber. I love that gun. It's not the prettiest gun though, but whatever gets the job done...

I've probably shot over two thousand rounds through it and I haven't had any issues with it. The recoil of the .45 on the HK full size isn't very bad at all.

Sigs are good guns too. My sister and another friend have a P226 (i think) in .40 caliber that shoots very smoothly.

You can't really go wrong with a Sig or an HK, but if you're on a budget, you can also look at the Springfield XD. I've shot them once at a range and I thought they were just ok. Nothing to write home about, but for the price, they get the job done and they get great reviews.

Shotgun also works. I prefer to leave the stock on it though. Shotgun is cheap and effective...

I also would not buy a .22 for your purpose for the reasons everyone already stated.
