I've been looking at many CZ pistols, as well as some clones, and I've noticed that they are very hard to find suppressed. I'm mainly talking about 9mm 75 pistols and their clones. I've heard that there are threaded barrels made, but it often seems to be "a friend of a friend's uncle knows where to get one." So my question is this; why are threaded barrels so uncommon/hard to find? I'm considering trying to get an EAA witness elite stock 3 at some point in the future and my mind just naturally wandered to the thought of a nice can. Thank you for your time. -Ben
