Who suppressed their glock? I am thinking about getting an AAC Tirant for my Glock 21. How many DB's would a suppressed .45, .40, and 9mm be? Who makes the most durable and tough threaded barrel? Will a lone wolf barrel hold up to more abuse and last longer than a regular barrel? How much more does 100 rounds of 230 grain ammo weigh than 100 rounds of 180 grain ammo?
