Super 9? Just FYI the .38 spl came long before the rest of the rounds you are talking about ....even the .45acp so you might say Hybred .38 splpeople debate 9mm or 45acp, how about the super nines. the super nines have more power then the 45. some times it is nice to be different. the super nines are the 357 magnum,38 super,357sig. and the 9x23.
