Beretta

I hold the love of my life in my hands
She is beautiful, as she gleams and glistens in my hands
Shining only for me, I stroke her all over
She squeals as I touch her in all the right places
She speaks only when spoken to
I know she loves me back, because she is willing to kill for me
All I have to do is point
Everyone that ever wronged me falls before her
She screams the harshest words as they meet their demise
All of my friends say that I need to leave her
That she is bad for my health
But I don't think I can live without her
Her power seduces me
She is always by my side
Even as every one turns on me
Who is she?
What is her name?
Her name is Beretta
