I did not know that 10 mm would work in a 9mm/38 super/ slide. I thought 10mm were switched with 45acp slides also 40 S&W will switch on 45 slides.
Sounds like a nice pistol though. Congrats !
Bob says Kimber cuts the breach face the same for 9mm/38 Super as they do for 40/10mm. Most others do not.
