I'm kinda on the fence about buying a suppressor. If I buy one, it's gunna be a 9mm. I have a couple questions. 1. Will a 9mm suppressor work on a .380? I'm guessing yes, since a .380 is essentially a short 9mm...but want to make sure. I ask because I want to get a Walther. 2. What is the most economic, compact, and quite can put there? I'm sure there is no prefect one, but what is the best of all three worlds? If it matters, I'm planning on using it on my G19, P228, 92FS, and a Walther PPK.
