Need upgrade recommendations for my EMG STI TTI JW3 2011.

What upgrades do y'all recommend? It's completely stock right now and I'm trying to get the max performance I can out of this gun. Willing to upgrade internals and externals, just need some recommendations on the specific parts.

Edit: I already purchased/have 5 30rnd mags, 1 350rnd drum mag , a tracer unit, a flashlight/laser unit, and an extra outer barrel, so I don't need those.

The feeding ramp should be polished to a mirror sheen. reinforce the slide. And tighten the interlock with the frame for added precision.

Keep the sight system original, too. The thumb safety should be extended to make it easier on the finger. A long-type trigger with non-slip grooves. A ring
hammer... The base of the trigger guard needs to be filed down for a higher grip.
And not only that, nearly every part of this gun has to be expertly crafted and customized. Where'd you plan to get something like this?"

What do mean by "Where'd you plan to get something like this?"? If you mean the parts, I'm not sure. Do you have specific links to the parts that you recommend?
