to some they may not need mods but i did the baisics ext slide release, mag release , pin kit , skull back plate just for looks , stainless steel guide rod and i bought a ported and polished 9mm barrel just for extra fun if i want to swap out the factory barrel i also polished the feed ramps of the origional barrel. Polished the exposed area of the chamber and the end of the barrel just for looks as well i don't know how to post pix or i would show you but eventually you'll see. Try looking at pictures in the pix section. Now i'm just waiting till i can get a crimson trace laser grip and a good tac light, i hope to change the factory sights to night sights and maybe a hogue grip i'll see. I do have trigger parts but i'm not sure yet. Most of the first upgrades i stated i think are the most important it feels a lot better to me. have fun !
