No reason not to trust 9mm. Granted, your Kahr has a lower mag cap than most other 9mm's.... BUT I EDC a Glock 17. I can tell you that I prefer my G17 with 17+1 rounds of 147 gr 9mm than a 1911 with 7+1 of 230 gr .45 ACP. Not that anything is wrong with a 1911 either, but in my humble opinion, twice the number of 9mm rounds on hand is just as good--if not better-- than the other option.
I understand where you are coming from though. I felt strange alternating the G30 and the G17 for a while. Both were outstanding, both had more than enough mag cap (i carry extra mag as well), and both have a proven record of getting the job done. Something about .45 ACP gives me the warm & fuzzy though.
I dont know. Flip a coin and carry both.
