I would use standard pressure 148 grain wadcutters.
I carry wadcutters in my 442, and have fired literally thousands of rounds through the gun with zero issues.
The ammo that I use is ammo that I have manufactured myself (I own a small custom handgun ammunition manufacturing company, Lost River Ammunition Company). With that said, just about any full wadcutter from a high quality manufacturer should work, provided that it provides some decent velocity and accuracy for you.
When I developed a load for commercial purposes, one of the things that was kept in mind was people who would be using it as a carry load for their snubby handguns. With that in mind, I developed a load that provided a little better numbers velocity wise, but was not a +P load.
Most factory wadcutters when fired from a 1&7/8ths" barrel are often only doing in the high 600s and low 700s at best. In a 4" I discovered through testing that most were doing in the low to mid 700s.
The load I produce runs 828 FPS from a 4" gun and 757 from a 1&7/8ths" J Frame. They averaged about 75-100 FPS faster than some big name brands, and had the accuracy I was looking for. Been using and carrying that load for years now.
But regardless of brand, I would opt for a standard pressure wadcutter, and make sure it shoots to your sights, or close to your sights and then get some practice in.
