Alx, I would expect a slower opening of the toggle and a faster closure, so the difference would be negligible. I just worked on a tired WW1 PO8 for a forum member that had a WW2 21 turn recoil spring installed and a few other minor problems. Unless everything is working properly (mag spring tention, right power ammo, smooth working extractor & poished feed ramps) the more powerful spring just causes problems. TH

Hi Doc:

Yes, the timing of the springs are critical to proper operation.

The Interarms recoil spring you sold me, coupled with an Interarms magazine, now make my 1917 DWM work perfectly, and with modern strength ammo.
