I think Wilson Combat has announced they will stop making guns in .38 Super, .40 S&W, and some hot-rodded .45; either .45 Super or .460 Rowland.
Apparently, the once thought left-for-dead 10mm is still an option.
Where did you read this "announcement" on the 40 S&W and 38 Super?
I ask because I see that they are still selling guns chambered in both and still selling their ammo for both.
