    There's not much difference in the energy levels of the two rounds. The hand loader can push the 38 pretty hard in a strong firearm.

    I don't have a 9, so I prefer the .38+P. Both are okay. I carry .357 magnum anyway.
    Sometimes a full sized 1911.

    Which has better stopping power, a long bow arrow, crossbow bolt, or an arrow coming from a compound bow hitting the same vital organ? ;) Gotta love modern ammo discussions. I'm sure men from many moons ago never gave it a second thought. Dead game and dead men are just that.

    They're about the same.

    Depending on barrel length, grains, +P options, you'll get slightly different results but both rounds are in the same ballpark, given equivalent JHP ammo. The .38 does allow for rounds like the Buffalo SWC, which you can't fire in semi-auto. The 9mm will usually offer more rounds, so it all sort of cancels out.

    Same diameter bullet, using a premium HP in each, but one carries greater KE-
    Greater KE likely to result in quicker incapacitation, other factors equivalent:
    Generally speaking, a 38 snub might produce 200-250# KE versus 325-375# KE from +p loads out of a Glock 26
    9mm > 38
    No internal lock or magazine disconnect on my pistols!

    More a function of bullet than velocity. Since an auto loader is limited to what it can feed, and can be beat to death by higher pressures, taking both to their maximum, the 38 spl handily beats the 9mm.
    Ignorance is a long way from stupid, but left unchecked, can get there real fast.

    if you want "stopping power" its often going to be the 9mm, if you have a 9mm gun with say like 15 rounds in it, compared to a 38sp with 5 to 8 rounds. For one shot... who cares, it depends on shot placement.

    Snub nose 38spl at 1 7/8 barrel length should not
    be compared against a 3.42 barrel length Glock 26,
    you can rig anything to fit an agenda.

    Both are fine, dependable stoppers when stoked with quality defensive ammo (no gimmicky junk). Past that? It's ALL ABOUT shot placement. Capacity is more about practice, 'cause only hits... count!

    I like them both terminal performance will depend on shot placement. Platform of origin i.e. barrel length. Not to mention most folks will keep injecting felon repellent till the problem no longer manifests itself.
