The hold open spring cannot be fully "activated" when the action is closed; the catch of the hold open will bear against the bottom of the bolt.

You can check this condition to satisfy yourself by removing the right grip, and trying to push the hold open "up". You can't. Then open the bolt and see how far it moves when "latched" open.

It is the magazine spring that will be slightly depressed since the hold open cannot move up. A weak mag spring or a worn button is
a common cause of failure for the hold open to engage when the mag is empty.

The hold open spring is always under slight tension, that is what keeps the hold open down in its
slot. Tension increases when the bolt is retracted and the hold open is pushed up by the mag button.

I believe you are worrying unnecessarily about stressing the hold open spring. JMHO
