WRONG The first N frames were the 38/44 ,which

were the first 357 loaded to near mag loads ,which brought about the REG MAG

that S&W brought out in 35,then the Mod 37,28 ect.

The Mod 25 though big framed will not take the high pressures the 29 will.

Many have abandoned there mod 25 because the 45acp has the same balistics.

Now the New Blackhawk will take any 45 colt loads you care to load!

First N frame was the Triple Lock, New Century in .44 Spec. brought out in 1907.

First .357 Magnum was the Registered Magnum, later called the model 27, brought out in 1935.

First N frame .38 Spec. was the 38-44 Heavy Duty brought out in 1930. The ammo for this was called the 38 High Speed or the like, but differed only in velocity from the 38 Special, to the best of my knowledge.
