The 380 and 38 special are both actually 36 caliber bullets.
A 45 acp uses what is actually is a 45 caliber bullet.
A 45 bullet is 20% bigger in diameter (versus "38"), not comparing weight.
In terms of power, KE is a common measurement.
Out of my guns:
Ruger LCP 380: 90 gr. Federal HS @ 878 fps = 154# KE.
S&W 442 (ported) 38 special: 110 gr. Winchester Silvertip @ 821 fps = 165# KE
S&W 442 (ported) 38 special: 130 gr. Winchester +P @ 848 fps = 207# KE
Glock 36 (45 acp): Winchester 230 gr. Ranger T @ 874 fps = 390# KE
