I have a 220 Carry Elite Dark, which came with that same skinny "short reach" trigger. Mine was annoying me when dry-firing and shooting the gun in DA mode, as it kept pinching my finger. I finally found a standard thick 220 trigger and recently installed it. It makes a big difference in comfort for me. So if you notice that skinny trigger bugging you, you may want to consider it. FYI - swapping the triggers doesn't affect the SRT (short reset trigger) mechanism that comes on the Elites.
Has your rear sight stayed put? I picked my Elite up brand new, and after the first 20-30 rounds, my rear sight was loose and required a re-tightening with their included little wrench. I hear this was a very common problem with these adjustable "combat" night sights. But 700 rounds since I tightened it, it has stayed put.
One more note - long OAL self-defense rounds such as Hornady's 230-grain T.A.P. +P were just a hair too long for my stock magazines. I've read that the newest 220 mags (8 round) are shaped just a bit differently than the older 7 rounders, so some long hollow point bullets can hang up with the newest 220 mags.
