New Stock, your Pistol really needs nothing except to be practiced with. Both Live Fire and Dry Fire (with a Snap Cap) will work in the action very nicely.
Down the road, once you have some miles on it, consider a Wolff 15 lb Extra Power Recoil Spring.
Taurus PT92 w Pachmayr Grip and Ghost Ring Rear Sight
This pistol has some 23,000 rounds thru it and is still going strong. It has been refurbished with a Wolff 15 lb Recoil Spring, New Firing Pin Spring, and the new Beretta Long Life Locking Block.
