Maybe you plan on using them for life, but I imagine most end up forgotten about in the back of the safe after they get replaced with newer and better technology. They are a money pit to be sure, one that most will never recoup a single dollar from.
Yep. Once you buy a suppressor , unless you plan on taking a loss its yours for life. I refuse to lose that so I just find uses for them. Like my AAC evo CQB-9. It aint worth a damn suppressing a 9mm. Works great with the 32acp.
