[QUOTE=EDIT Is there a valid reason to stand the expense of the .45.[/QUOTE]
I like both rounds, fast little 9mms and slow fat .45ACPs. Both will do the job. I have a handgun for every room so 9mm, 45ACP, .38spl., .357mag., .44mag/spl., I trust my life to them all. My "valid" reason for having a .45 is because I enjoy shooting it. That said, I have two 9mms and don't plan to replace them with .45s. Liive a little, get one of each!
