Wolf springs for the luger are "all over the place" with respect to length and "power".
You may or may not be improving your situation.

As you can see from the chart, the Germans(or someone) could not exactly make up their mind what spring was needed! JMHO.
Of particular note are the springs for the 1920 and 1923 commercial lugers- 7,65mm and 9mm the same-but '20 and '23 are different from each other, as the kids say- "go figure". I realize these are from measurement and may not be totally reliable, but are offered to put mainspring variations out for consideration!

I have used Wolf springs, but only after measurement. The first Wolf "Kit" I bought had 3 different stregnth mainsprings or was supposed to; the 34 lb spring was longer and stronger than the 38 lb- at least the way they were labeled.

If you must mess with your spring, take it out, measure the wire diameter and number of turns and the free length. Compare with the table that is available.

Then decide what to do, and by all means compare the "new" spring to the old and the chart.
