If the cartridge is too much for you go down a "caliber"
Recoil buffers
may reduce felt recoil a bit, but usually they are more about improving durability than shootability.
Some makers (like CZ and Beretta) actually include recoil buffers in some of their designs. Many would say that if the manufacturer didn't put one there then it's not needed. I've never seen one that could actually cause harm to the firearm but they can, in certain circumstances cause function problems, particularly when/if they start to break down.
I don't see any problem with using them at the range (and I do in some of my pistols) but would
never use them or recommend them for use in a pistol while it is actually "on duty" doing home- or self-defense unless that's how the pistol came from the factory.
