This is definitely the one attachment that 95% of people use on PC. For me, it is pure gold. I do miss hearing the refreshed weapon sounds in all their glory but it is worth the sacrifice for the stealth factor. I don't think the suppressor affects the gun performance too much regardless of what the stats say and as this game is driven more by sounds than any other COD I've played; firing at full-rate can really draw attention to you even from a reasonable distance.
Does anyone on here not use the silence on all their weapons that are applicable and how many proportionally opt for the attachment on the consoles as a whole?
