There are a lot of C naysayers. You should try firing 25 shots with a 21C and 25 shots with a 21 non compensated and see which hurts your ears less. From what they say the non compensated sounds like a suppressed .22LR while the C sounds like a 12 gauge shotgun. :chatter:Please tell me if you EDC your Glock 21c, and why. Thank you I am new and would appreciate your feed back.
