I’ve heard that you can stop a 9mm with a lot of layers of clothing. I suspect that the 25 auto is only useful in the summer against people in a t-shirt.
You heard wrong.
In one example a paroled con went to murder a woman who helped his wife divorce him. He shot her through the heart with a 9mm FMJ. The bullet went through her, through the wall behind her across to the next apt bldg and passed through another wall and finally buried itself in the wall above a sleeping couple. Don’t buy caliber hype. 9mm is extremely effective and deadly.
“I’ve heard that you can stop a 9mm with a lot of layers of clothing.”
You may have heard that, but it’s bullshit.
You heard wrong...from someone who doesn’t know.
It is actually true.
It just needs to be about 20 feet thick, of layered clothing.
The meat target results suggest otherwise. (time index 10:50 or so). As you can see, about the same penetration as .357 magnum in this test (albeit with less damage done via tissue shock).
