If Japle is promoting their use, then I apologize. But I have to say that silencers are a very practical item to own.
For some folks, they may be practical. Not for me. I’m buying one just because I want one.
It’s the same reason I have a $3,000 SteelMaster. I could shoot steel with much less expensive guns (and I do), but I wanted the STI, I could afford it and I bought it.
“Practical” and “need” are irrelevant. Your budget and your desires are what count.
