Got it...I also shoot 180 grain JHPs in 40 S&W, I consider loading the 40 at the low end of its range for any given powder as a 9mm magnum while loading it at the high end of the range as a 45ACP magnum with 185 grains JHPs. So, you might say the 40 S&W is a three-caliber gun. Anxious to get my MK9 and the search for a K40 is still out there. Stay tuned...
