In 20/20 hindsight, I should have wrote "approaching" rather than "comparable". How closely it approached .357Mag varied greatly. Some +P+ loads were better characterized as "warm" rather than hot.

Exactly. FWIW some of it was loaded for .38Spl rather than .357Mag revolvers, and these particular loads tended to be only "slightly warm". IIRC in an older thread about +P+, a poster claiming to be a former cop reported that one of his department's .38Spl range guns- a S&W M67 if I remember right- had fired 5,000+ rounds of a "warm" +P+ load without substantial damage; its lockup was reportedly getting loose, but it still functioned fine and shot accurately.

The key, however, is that +P+ loads were NOT created equal, and should NOT be fired in a .38Spl revolver unless you are certain that the specific load you are using is safe.
