I don't understand some of the hate I've seen for the Blackhawk 10mm/.40 since it was announced late last year.
Yes, it's not a common caliber for a single-action revolver. And yes, there is a fair amount of overlap in terms of performance when compared to other calibers. And yes, you can get other calibers in the same gun that are either more powerful, or softer shooting.
But at the end of the day, we're talking about a product improved version of an obsolete technology. There are other gun designs that have more capacity, less recoil, are easier to reload, with more efficient "standard" calibers, that are lighter, handier, more comfortable... And I could go on.
At the end of the day, we shoot revolvers because we want to. I want a 10/.40 Blackhawk, just because. And that's a perfectly legitimate reason. Sure, I could do the same thing with a .357 Mag. Actually, the majority of the guns I have chambered in .357 are not revolvers. Again, just because I can.
So for those who don't want a revolver in .40 or 10mm, don't get one. Problem solved.
