This year is going to go by, and at the end of it you can either be a year older, or you can be a year older and have a silencer.
There are three distinct silencer groups to cover everything: Centerfire rifle, centerfire pistol, and rimfire.
Overbore is fine, .45 can works for 9mm, .308 can works for .223, .22 can works for .17
But you don't want to mix between the categories much.
I guess four since shotgun silencers exist now.
A centerfire rifle silencer can get too hot to grab in as little as one shot.
For me, the "balance issue" I found was the rifle being muzzle heavy while shoulder slung and wanting to pull down backwards. I got a really long shotgun sling, and ziptied it closer to the muzzle to fix that.
Some people think that you need to use subsonic ammo for a silencer to be worth it, and therefore centerfire rifle cans are stupid. IMO that's wrong. Making a .30-06 sound like a .22LR, while not Hollywood Quiet, is absolutely an improvement.
Individual opinions may vary on whether or not you still need earplugs with a silenced rifle.
With a long bolt action out in the open I say no, with a short AR under a shelter or in the trees I say yes. In between is in between.
