Having had fired a shotgun a few times in excitement without putting my ear-pro in as well as an ND when I was new to guns I've experienced that shooting off a load without protection is pretty painful. In the unlikely situation I need to fire a weapon in defense of myself or other occupants of my home the last thing I need atop the psychological and legal complications is hearing damage/loss, so I'm thinking about a platform that if I put a can on it would be hearing safe. The two calibers that come to mind immediately would be .45 acp and .300 Blackout.
Due to personal preferences I'd like to avoid AR platforms, as well as anything with a floppy dead-fish trigger like a Glock, I'd like it to be shorter than if I stuck a can on my PTR91, but having a higher capacity and/or a stock or arm brace would be a big plus. I saw another HK clone in .300 BO but its 3k so that's not really a viable choice. I'm thinking mostly of either a Vector in .45 acp or a Tavor in .300 BO. I've always wanted a Tavor so that'd be a plus but watching one of MAC's videos I saw that the pop from the ejection port is in the low 130s of Dbs with subsonic ammo and the high 130s with super sonic ammo. I was of course thinking of the sub stuff but it only has the ft/lbs of a .45 acp.
I'm not that huge on the Vector but in the pistol configuration it'd be compact, takes Glock mags, and can take an arm brace. The ammo would be a lot cheaper but the can would be a lot more, plus I'm a little squirrely on what counts as a "hand stop" and what is a "vertical foregrip" since holding the front of the magwell on a Vector is a good way to accidentally drop your mag. I suppose I could also just get an FNX-45 but that wouldn't have a brace, lower capacity, and still has more expensive cans.
Is there a blind spot I'm missing here of a better option? Or is my dislike of ARs and Glocks kneecapping me that severely?
