A very long time ago, when I was serving in the NYPD ’s Firearms & Tactics Section (as a Sgt., and later as a Lt., I ran the Police Firearms Instructors School, Heavy Weapons Training and Research and Testing) I visited the Remington factory in, I believe, Connecticut.

Speaking with one of their engineers, he stated that .38/.357 wear on revolvers was less intense with projectile weights from 140 through 158 grains. He stated this was due to these rounds less abrupt “time-pressure” curves.

I’m not an engineer but have followed his advice ever since.
