You want target wadcutters, Federal loads them as does Fiochi and I'm sure others such as Remington.
The good old target 148 gr wadcutter is very pleasant to shoot and excellent self defense ammo, just not as sexy or expensive as the gee whiz stuff.
Rpg offers good advice here. Ok, here's my true 148 gr. wadcutter story... when I was a teenager, I was a bellboy (yeah, this was a loooong time ago) at a local chain motel. One of our regular customers was a nice gentleman that everyone on the hotel staff knew because of his frequent visits. One day, he asked me if I would do him a small favor and buy him some flesh and brown colored enamel model paint (at the time, you could go to any model shop in town and get the tiny bottles of paint for maybe $0.50/each). I brought him the requested paint bottles and a couple of paint brushes the next day and he asked me to follow him to his room so he could repay me.
Once we got to his room, he invited me inside and got his wallet out of a desk drawer to pay me. That's when I glanced into the open drawer and saw a well worn S&W Model 60 - and his credentials. Turns out he was an FBI agent. When he saw me looking at his revolver and credentials, he explained that he specialized in what is now known as hostage negotiation, only his was of a more dynamic nature in that he actually went into the bank to talk the bad guy(s) out. He took the Model 60 out of the drawer, opened the cylinder and handed it to me to look at. I was surprised to find he had it loaded with, you guessed it - 148 gr. wadcutters.
He explained that if he had to shoot someone it would probably be at close distance, and that he might require multiple shots. Thus, he wanted something that wouldn't over penetrate, and had mild recoil. Oh, and as for the model paints - he blended the paints to closely approximate his own skin tone and slathered the paint all over the Model 60. He explained that once painted, he could "palm" the piece and it would be effectively camouflaged. A lot to absorb by a 16 yr. old kid - that guy blew my mind!
As an ER nurse, I've seen what happens when someone is hit in the belly by a 148 gr. wadcutter at close range and it is not pretty. They make an effective antipersonnel round in my opinion.
Mgriffin - you mentioned you have laser grips on your Model 442, but you didn't mention what model/make they are. I have arthritis in both of my hands and wrists, so recoil management is important to me. I use Crimson Trace LG-405 laser grips on all of my Air Weight J-frames as they are built with a hollow chamber along the backstrap. This chamber compresses under recoil and helps mitigate recoil quite a bit.
Good luck,
Dave
