Recoil spring, main spring and FP stop plate changes can all reduce battering. I tend to do the "quick and dirty" recoil spring mods, myself.
One does need to be aware of the possibility of reverse battering with stronger recoil springs. There are limits you do not want to exceed.
KISS is my major bias against buffers. If you keep fresh replacements in stock, keep a close eye on wear and know your pistol tolerates them well? Then, I am not going to get too uppity about it.
