I'd give Winchester target loads 130 gr a try. They come in a white box and are cheap. Walmart usually carries them.

Pretty mild ammo.

It's what I use for practice with light weight guns like the 442 and 642.

The wadcutter idea is also a good one, but I usually have trouble finding wadcutters, and they aren't cheap.

Remember, to be effective, a gun has to have some power behind it. So, to some extent, you just need to practice enough to get used to some recoil. It kind of comes with the territory.
