I carry my SP101 with a 2.25 inch barrel in .357. In the summer for better concealment its a shield 9mm. I have never shot the .357 without hearing protection, and have always been afraid of what that may do to my hearing if I did have to shoot it without hearing protection. Especially since I only have hearing in one ear, due to losing the hearing in my other ear when I had mumps at 5 years old. I'm very cautious with the hearing I have left, and it worries me at any time having to possibly shoot my short barreled 357 without hearing protection. Especially if it was indoors. For that reason I have been thinking of switching to 38 +P rounds. Anyone ever shoot a 357 indoors with no hearing protection? If so what did it do to your hearing?
