Kensington Expert Mouse. Trackball superiority, baby. Plus scroll wheel, 4 buttons, chording inputs, macros, program-selectable specifications, the works. Also, wireless. Or, if you get the wired one, the cable won't fray because it never moves.

You have identified the problem exactly. There's virtually no difference at all between the two barrels as you described. Eventually, maybe, there might be microscopic differences between the two if both of them have been used a lot, but even then it's not the "focus, magnify, magnify, enhance" crap from NCISSICCIENDUF:New Orleans:SPUWIOM.

Ballistics matching is a thing, but it's not the hah, magic bullet that Hollywood has made it out to be. If you can recover a bullet and a gun, and you run them through an analysis, it's generally possible to match the lands and grooves of the gun barrel to the mechanical deformities of the bullet. Glocks initially caused a panic when they were introduced, being mostly plastic and having polygonal rifling, because they were "undetectable plastic guns with barrels that left no trace". Bull, of course, but a good political talking point.
