I have a strange question- I live in rural eastern Oregon, and usually carry some kind of gun with me in the truck for the occational badger, coyote,rattlesnake, rabit,etc. I end up walking around looking at old homesteads, cars,and such so a lightwieght hand gun that I can put in my back pocket is what I prefer. I like something larger than a .22, and my current choices are 2 1/2" S&W 357 (with 38sp.), Kahr K9 9mm, and a Springfield commander sized lightwieght 1911 .45acp. What is the Quietest out of these? Is there another caliber that is quieter? (besides 22) I never target shoot without ear muffs, and I have sensative ears, but out in the field I don't usually carry ear protection (varmints move fast!!) I do handload, mabe I should have posted there, but I will try here first. Thanks in advance-
