Installed a C&S lightweight sear spring and replaced the mainspring with 15#.
Result is about a 2# trigger pull. Ran my handloaded 124gr xtreme bullets using CCI primers and 4.4gr titegroup. Comes out the barrel at 1177fps. Ran through approximately 100 rounds with no felt recoil at all with no light primer strikes.

What is the OEM weight mainspring?
-
18lbs. Lots of folks are downsizing to a 17 Wolff. That's what I'm going with for my DWX.

1177fps with a 124gr projectile is a tad hot for that powder. Pipe-bomb, catastrophic hot. 4.4gr of Titegroup is above recommended safe loads in any of my books or resource materials. That powder normally maxes out in the 1030-1099 fps range with 3.8 to 4.1 grains, depending on projectile and case volume.
I can get there with BE-86 but not necessarily on purpose.
