今天看到这篇关于Indiana State Police警用手枪口径在过去30年的变迁,以及一些背后的因素:

In the last quarter century, the ISP has gone through half a dozen different types of handguns. The old standby .357 revolver with 125-gr. magnum loads was replaced in the ’80s by a double-action 9mm with 147-gr. subsonic ammo. In the ’90s, there was a switch to the same pistol in caliber .40 S&W, with 180-gr. subsonic hollowpoints. Time went on, and in the new century a striker-fired, polymer-framed .40 replaced the older style. Various issues caused another change, to the same model in 9mm. Toward the end of 2012, the department adopted a striker-fired .45 auto.
......
Confidence is inextricably intertwined with competence. One long-time Indiana trooper familiar with the controversy told me, “In the end, it was pretty clear what it came down to was the Superintendent wanted that trooper out there alone to have maximum confidence in what he or she was carrying.”
用自己最有信心的枪和口径,其他的,仅仅是debate而已。
