The Luger action is finely balanced. There were a range of recoil springs used in the different models and eras of Lugers. The forum FAQ document has a copy of the table.

Recoil springs came in different wire thicknesses with different numbers of coils.

If you remove the recoil spring, you can manually operate the action and feel if it is binding at different points in it's cycle, and especially toward the end of it's movement. If there is no binding of any kind, look to the possibility of wear or deformation changing the geometry of the hooks or s link in the recoil spring linkage. Also check for wear of the frame where the axel pin rides.

Removal and installation of the recoil spring is a fairly specialized job. It takes a properly designed tool to actually do it without damaging the gun or yourself. Use great care... it's under fair compression.
