Cops carried 38 revolvers for most of the 1900’s and until the late 70’s early 80’s did so with plain Jane non plus p with LRN, Ball and SWC and gave a lot of bad guys dirt naps so maybe we worry about the wrong things!
On the other side I will give you 38 Plus Onis a whole different round out of a 4” barrel compared to a 1 7/8th inch snub it doesn’t get the velocity to do what it does out of a snub but somewhere between 3 and 4” barrel it does.
Yet people live to stuff plus p in snubs with lightweight allow frame and then complain about its not easy to shoot them scoff when you suggest wadcutters in snubby guns
All about the marketing!!!
