Just for conversations sake, I offer this: 40S&W is now the preferred LEO caliber with no realistic change in sight. The US Military is ever increasing the # of units using 45acp & if they ever get back to selecting a new service pistol it looks like it will be a .45. In my area (& from some of the other posts I've seen), .40 is regularly in stock, 9mm is not, & the price of 40 is better than 9mm. All things being equal, .40 generally outperforms 9mm in terminal ballistics testing, or at least that's what most impressions seem to be. I'm talking strictly for the US market, what could all of this mean?
