Got this from Hickok's fb page
A few years old but still an informative study of shooting statistics
Idk if it can conclusively recommend one over another
My HD choice, 38sp, did pretty well

Georgia Mom Hiding With Kids, Shoots Intruder - ABC News

"Melinda Herman shot the intruder five times, hitting him in the face and neck."

Intruder survived shots from a .38 cal.

Great read. Thank you for posting.

I'll have to go back and read closely when I have more time, but until then. . .

Head shots = 75% immediate incapacitation

Kinda interested in what happened in the other 25%.   

Mostly joking.  I know there are instances where people get shot in the head and survive, like Gabby Gifford, but damn. 

i realize that this is only tangentially related, but i was recently having a discussion regarding the hearing damage that could happen to a homeowner in defending a house with a firearm.

I didn't realize that a 9mm fired from a pistol produced significantly greater sound pressure levels than a 45 Auto pistol and even an 18" barreled rifle in .223

Can any one verify these numbers, and does anyone know the SPL statistics for a pistol caliber carbine in 9mm and 45 Auto?

Even a pink 38 is deadly.

I wonder what type of 9mm ammo they tested?  I choose to use 147grn standard pressure.  It is subsonic and noticeably less noisy than the typical 115 or 124 grain supersonic loads. 

Choosing what projectile for 147 is key though, especially in shorter 9mm barrels.  Through research I like the Winchester Defend hollow points.
