You can get a "D" spring to lighten the trigger pull, however after putting a couple of 100 rounds through and more, it should lighten up, I've never bothered going with the "D" spring in my 92, or 96FS and I shoot the DA as well as SA, which is very well, just practice. After all the SA pull is as sweet as a target pistol and I know when I pull the trigger the primer is going to get hit hard w/ any ammo I choose to feed it. Beretta updated the 96A1 as it has an "internal recoil buffer" for durability and less impact to the frame, so the need to go to a heavier recoil spring is a non-issue w/ the 40cal 96A1. I run a Wolff 15lb spring in my 96FS. Likewise, the 96A1 incorporates a captive recoil spring assembly. If it were me I'd stick with it the way it is, change out the recoil assembly when needed and shoot away.
