I think this oft-repeated Internet statement is incorrect. The power didn't change. But the means of recording velocity did, making the newer ammo seem less potent. But it was really just a matter of publishing more accurate velocity figures.
Old figures were taken from long pressure barrels without a gap.
The current system uses four-inch barrels and they have a gap (vent) like that between barrel and cylinder on real revolvers.
If you have a good modern chronograph, try firing some ammo made from the 1920's-1950s and some modern loads.
Firing much Plus P ammo in old guns made of softer steel may result in aggravated progress of cylinder endshake.
The OP's theory that having a DA revolver means that he has a semi-auto pistol is too unfounded to
address. I hope he was joking. He seems to be BADLY in need of some basic gun books
