I have a 342PD. I carry it stoked with CorBon 125 Grn +P's.
I just came back from the range. Shot Winchester 125+P's and the Cor-Bons.
If you go by noise and recoil the Corbons produce almost twice the recoil and a louder noise.
CorBon ammo has a lot of engineering built in and is usually hot!
If your Airweight is not +P rated you can get the Chief Special Federal Nyclads. They chrono'd in a test as hot as some +P's with standard pressure.
They were specifically designed for Snubs.
The powerball ammo in my 9mm is hot too,
