Here are a few suggestions (I have done these by the way):
1. Wolff Trigger Spring- The Reduced Power one
2. Wolff D Spring- Made the trigger pull smoother
3. Wolff Recoil spring- I went with the 16 or 17LB one
The heavier recoil spring made shooting Remington 124gr +P much smoother and easier to handle. However I had trouble shooting 9mm frangible rounds with the heavier recoil spring. They would not cycle at all. But overall if your shooting bullets 115gr and up these upgrades will make for a much more enjoyable experience.
