If you are shooting any bullet at 1,000 fps out of a 2" barrel, you need to know if it is a J frame or heavier.

A 150gr bullet at 1,000 fps is really for a K frame or heavier, since the recoil is quite heavy and over pressure for any J frame.

Most powders like Unique or slower will push a 158gr lead bullet at 1014fps or faster with 38 special cases in a 6" barrel if you want, this speed.
In a 357 a Magnum case, you can get up to 1,000 fps with just medium fast powders.
In my 6" 686, Green Dot can reach 1281 fps.

Even though you can "Develop" high fps loads in a snub nose revolver..................
it is really nice to have a QUALITY Hogue, one piece grip (or other) that covers up the metal back strap and cuts down on the recoil and "Sting" of the high recoil loads energy.
The slim, factory , wood grips are killers.............

Manageable recoil at 1,000 fps out of a 21 oz. revolver with a
150gr bullet..........
Isn't happening.

Have fun.
