Pressure does not have to do with bullet expansion, the bullet itself and velocity determine expansion. Pressure is more related to the stress put on the pistol or revolver when the round is fired. Extremely high pressure can and sometimes does cause considerable damage to the firearm and the shooter.... It is fairly comparable to the popular 9mm round. ...
I wouldn't call them comparable. Not at muzzle energy energy anyway ... .38 runs from >200 to ~300 ft/lbs for a "+P" round. A 9mm runs ~ 350 to > 450 ft/lbs for a "+P".
For pressure a .38 runs ~20,000 PSI, while a 9mm hits 39,500 PSI. Because of the low pressure bullets don't expand well... meaning less take down.
I'll take a 9 over a 38 for self defense any day. For CCW, a .380 makes a nice compromise because of its size.
Math is math. Pressure is used to overcome friction and accelerate the bullet. .38's come out slower leading to less fps at impact. The .38 is not considered a very good round in terms of expansion... thus the development of several "soft loads" to compensate for the slowness.

Most .38 Special loads don't hit anywhere near that... most are around or less than 1000fps. I'm not trying to "dis" the .38 - I have one. Will it stop someone, yes. Does it have the same stopping power as a 9? Forget everything else, energy @ a given distance the 9 will have a significant advantage over the 38. Not to mention you can get 5 or 6 shots from a revolver, and I can carry 16+1 in my 9. Personally I'd rather carry .50 Action Express (upwards of 10 TIMES the energy of a .38) in a Desert Eagle, but kind of hard to conceal. Not mention the last time I looked they were running $1300 or so, plus almost $2 per shot.Hollowpoint bullet design facilitates turning the bullet "inside out" and flattening the front, referred to as "expansion." Expansion reliably occurs only at velocities exceeding 1200 fps, so is suited only to the highest velocity handguns.
I'm not a shooter, I know from nothing about guns and the last and only pistol I remember shooting was a Colt .45 off the fantail of the ship to "qualify" with a pistol as per my petty officer rating... second class PO was supposed to be "qualified" with a pistol.... I'm pretty sure I hit my target... the pacific ocean.....
But all the above sounds to me like " she said Potato and he said Potahdo"... :biggrin::biggrin::biggrin:
