My SD9 is pretty much stock. Wider take-down plate. A couple of patches of "skater tape" (e.g., 3M Stair Safety Tape) on the grips. A Warren Tactical Rear sight. Stock recoil spring. No trigger mods.

No lights (white or laser) hung on any of my pistols or revolvers. But I keep a Steamlight and a set of ear plugs in the drawer with the home-defense gun -- which is usually a revolver. So I recommend at least having a good flashlight and ear plugs nearby your SD9VE, plus of course an extra loaded mag.
