wolf 1415,
There is no point in trying to draw any conclusions from the guns that different agencies select. Let me give you an example of why:
In the last two years, let's say agency A and B both selected .40 S&W pistols for duty issue. A and B both formed committees, and had exhaustive "trials" to determine which gun to choose. A and B both tested basically the same pool of guns. BUT, in the end, A and B chose different guns. Why? Personal bias of the "committee"(er, old boy network) members, for one, is a HUGE reason. So and so may love Glocks, etc. Money is a HUGE reason. For example my agency will never issue Sigs, too damn expensive, etc. There are a myriad of reasons.
One agency I am familiar with chose one particular gun, then the same manufacturer came out with a polymer model and the firearms staff stated they would have chosen the polymer model had it been available when the test was done. And people out in the world buy the handgun this "elite" agency issues thinking it's the best when that agency has already determined something is better. Confusing? YES
In my opinion the best handgun is the one with the largest caliber, that can be shot at speed more accurately than any other, which dominates all "combat" pistol competition, which has been proven over 80 years to be a superior design. In other words, if I was on the committee, we'd be using a dehorned 1911 .45acp with big fixed sights and a 4# trigger as a duty gun. There's that personal bias I mentioned above.
As always, $.02,
