The price is beyond tough to swallow...that is, from my regular guy perspective.
For somebody else, it would be pocket change... Just like anything else that costs a lot.
It will be interesting to see other OEMs build Guns in this caliber.
Personally I think you don’t really need a proprietary caliber to achieve this performance. You could neck down a .357 SIG to a .3” bullet and 80-90 grains and get the same performance.
Heck, Underwood’s already busted the 600 lb/ft. mark with their .357 SIG loading, and that’s out of a 4” barrel.
