I'm an old dog so take it with a grain of salt.... I've seen too many people get wounded with 9mm. I'm a strict believer in the.45 because when it all comes down to it, I want a round that will knock 'em down if my aim isn't perfect. that being said, I just bought a CW45 after carrying a 1911 for years. As you get older your butt starts to disappear and move around to your gut, (lol). You want a lighter thinner gun but you also want one that will do the job if.. god forbid.. you need it.
