I’m familiar with the statistics around defensive and police shootings. Agreed, most shots are misses, but how would FMJ help with accuracy?? We choose our ammo with the assumption that we’ll make the shot that counts.
This is why we test until we’re comfortable with the reliability. Thankfully modern HP ammo is extremely reliable, has gone through plenty of R&D, has been subjected to FBI and other independent testing, and millions of HP rounds have been fired through pistols both in LE and consumer hands. I don’t think there is a strong argument for ball > HP when it comes to reliability of functioning.
Again, agreed, pistols are the least capable weapons for SD but that was the question posed here and none of us are carrying long guns on our back to the grocery store. (No, that’s not challenge to anyone haha)
