This is an older doc on defensive ammunition:

One thing it says is
I have a .38 Special +P LCR (not the 357). I'm wondering about the advisability of firing +P out of it on a regular basis. I try to practice as much as possible with my carry gun using rough equivalent to the ammo I carry (can't afford to go through boxes of hollowpoint on the range).

One thing it says is
Standard pressure loads may be used in any .38 Special revolver, but +P
loads should be fired extensively only in steel-frame .38 Special
revolvers. Firing a few (under fifty) +P loads in your aluminum-framed
.38 Special revolver will not destroy it or cause it to explode, but will
damage your aluminum-framed revolver if you fire more than a hundred
rounds.
