Every cartridge has a standard SAAMI pressure loading so that gun manufacturers can build to a specific chamber strength. +p and +p+ rounds are loaded hotter than the standard and should only be used in guns capable of safely handling the additional pressures.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)

"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington

FWIW, there are only a few "real" +P loads- 9mm, .38 Special, .45 ACP, and ALL .38 Supers. Those are the rounds for which SAAMI established a +P load. They are loaded to about 17% higher pressures IIRC. While someone may CALL another cartridge a +P, there is no standard for other cartridges.

The +P+ is loaded hotter than a +P, but again, there is no standard for that load- so in theory, you would load that up as a 2 times pressure load.

SOME handguns- especially older ones, were not designed for the higher pressures. Unlikely to have an OMIGOD! kind of failure, but will cause accelerated wear on the gun.
What we have here is... failure- to communicate.
