Feel free to point out my stupidity if anyone thinks I am a wackjob for doing this, but does anyone else adjust their caliber choice to coincide with the seasons? I am not a ballistics expert by any means but when cooler weather rolls around I like to up my caliber choice. I do this because I would rather have 6 rounds of .40S&W or .357sig in the winter time than I would 7 rounds of 9mm. The main reason being the fact that in the winter months badguys are more likely to be wearing heavier clothes. In my own non-scientific tests at home (Using my PM9, MK40, and P2000SK) I have noticed that .40S&W and .357sig do a better job through denim and fleece than similar 9mm rounds. So I am heading out today to pick up a Kahr PM40 (similar to the size gun I did my testing with) to replace my Kahr PM9 for the winter months. When summer rolls around again, and people are wearing lighter clothes, I will go back to the higher capacity PM9. Thoughts?
