G17 gen 4. Add talon grips and you're down for a base set up. Apart from this, upgraded tru glo sites (on my list to buy).
Accurate, easy to field strip and clean, no misfires after 800+ rounds (majority used AE ammo and about 100 winchester).
Aside from this, a Blade tech belt and Uncle Mikes holster then youre done. Forget the surefire lights and shining extra accessories, save the money for ammo and targets, then become proficient with operating the pistol.
