Best? Probably not, but for sure in the top 5.
That's like saying "strawberry" is the best ice cream ever.... There are so many very good 9mms... I doubt that unless one puts some condition, "the best all steel" or something, that there would, or could ever be a "best 9mm".
Although there's a bunch of guys that recently bought Sig P210 Swiss army surplus guns that would argue strongly for that gun!
And when there was a change in sidearms. Many Police Officers purchased their 5906 instead of turning them in.
The only real problem with most of them is holster wear.
