40 S&W Taurus PT 101SS Accessories

I had an earlier post for a laser. I would like to also research some other options for my pistol. I am interested in entering some tactical shooting at my local gun club. Does anyone have any information or links where to find tactical accessories (i.e. ported barrels, hi capacity mags,matched trigger sets, ect) that will fit the Taurus PT 101? Also any recommendations for any upgrades for this pistol.
