I wouldn't trust any handgun cartridge to break the pelvis, let alone perforate the femoral artery.I agree, shoot until the threat is no longer a threat. I like to start low and ride the recoil up. Pelvis, abdomen, chest, head.
The pelvic shot is good for an attacker armed with a knife or club. When you break the pelvis, the body cannot stand and will fall. I would not trust a 9mm to break the pelvis. I only consider this with a "Major caliber". 40, 10, .357 or 45.
+1+Shoot until the threat stops. If it only takes one round, then only shoot one round. If you empty your magazine and have to reload, do that. There is no magic number.
Bingo. Rifles have field days with pelvis shots, but there's simply not enough power in most handgun rounds. And keep in mind that most people survive gunshots by handguns. Most don't when shot by rifles. Keep shooting until the fight is over.I wouldn't trust any handgun cartridge to break the pelvis, let alone perforate the femoral artery.
The area of the pelvic girdle that is necessary to hit to deliver incapacitation is smaller than a human head. Add in the fact that the pelvic girdle is nearly impossible to break, unless from a straight-on shot (face to face with the attacker) I'll take my chances with a shot to the brainpan.Something else to consider when aiming for the pelvic region or there abouts is the bladder I hear is not pleasant to be hit especially when full.
I agree that there is no sure method to drop someone with a pelvic shot but let's consider (and this happened several years ago in oregon) the bad guy has body armor. Under stress a headshot is difficult and even more so if they are returning fire on you.
Good thoughts flowing here.
