口径的争论，最终还是决定于信心

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：

http://americanhandgunner.com/caliber-choice/
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。

过去30年来，人的平均身高体重在增加，所以需要更大的子弹！

Defective state police guns to be replaced

Indiana State Police will receive new Glock 9 mm handguns as a result of functional problems with their current Glock 40-caliber handguns.

About 50 guns that were identified as dysfunctional through a manufacturer defect will be replaced, said Indiana State Police Sgt. Joe Watts.

The manufacturer is replacing the guns at no cost to State Police, Watts said.

No timeline has been set for when the new handguns will arrive. When they arrive, police will be trained on their use.

State troopers can carry one of the new, replaced handguns or the gun previously carried, a Beretta 40-caliber, he said.

Last year, State Police replaced their old Berettas with the new Glocks.

"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.”

这个难道说的不是superintendent一拍脑门决定下面用什么？下面每个人能力不一样，众口难调，用什么有信心superintendent怎么知道？
