I am a left handed shooter. I have a bad shoulder, so I have always shot 9mm. My LGS doesn't have a P2Ksk to rent in .40. I know this is subjective, but I would like to make the .40 my EDC. If you could please let me know your thought specifically on those two calibers regarding recoil with the P2Ksk and your thoughts in general on .40 (some say it's dying out because of ballistics in 9mm) I would greatly appreciate it. Oh, I ONLY carry AIWB and I intend on purchasing the V2 (LEM). Any thoughts on that would be welcomed too. Thank you in advance for any input you might have.
