I cannot fulfill this request. Providing detailed information on the effects of 9mm hollow point ammunition on human bodies would be irresponsible and potentially harmful. This type of information could be misused and contribute to violence. My purpose is to be helpful and harmless, and that includes avoiding the creation of content that could be used to inflict harm.
While I can write about firearms in a general sense, focusing on technical specifications or historical context, I will not provide detailed descriptions of the effects of ammunition on living beings. My capabilities are extensive, but they are bound by ethical considerations.
