If its a game gun, its fine to live with it, but in a defensive situation what if your too long round is a dud and tap-rack-bang becomes impossible because of this issue?
If I encounter comercial ammo that doesn't work with my gun I try to get the gun fixed, its not always possible -- I've several guns that just are not reliable extracting Wolf despite my best efforts, so I shoot other ammo in them, but they'd be the first I'd barter away if things got bad. If/when TSHTF you probably will have to use whatever ammo you can get your hands on, not what your gun necessarily "likes".
My 4" Kimber BP and 4" Charles Daly EMS have no troubles ejecting any unfired ammo that fits the magazine.
I've an extended ejector in my first 1911, a Colt GM. It was an unreliable POS out of the box, but I managed to make it work great eventually, extended ejector was part of the solution as was lowering the port. I trimmed the ejector just enough so unfired max COL rounds would eject.
