True but only very extremely slightly and only largely in regards to trigger return tension. The chief spring tension exerted upon your trigger will be when you cock the revolver and the mainspring in the grip exerts its tension upon the hammer which in turn exerts that tension upon the trigger's engagement surfaces with the hammer. You overcome and feel that tension when you pull the trigger (after you have first taken up the slack).
That chief grip mainspring tension will not be affected by lightening the bolt/trigger spring's tension. Model-P is technically right, but the bolt/trigger spring tension is so minimal to felt trigger pull weight with a cocked hammer as to be inconsequential. The only felt tension the bolt/trigger spring exerts upon the trigger is the tension you feel when you take up the slack in the trigger before you feel the increased tension when you come to moving the engagement surfaces (sear) of the hammer to trigger. Lessening the bolt/trigger spring tension will only slightly decrease the tension of the earlier mentioned taking up of the trigger slack. And the taking up of that tension in that slack is necessary because there has to be some tension on the trigger to return it forward after firing. Otherwise you would have to manually return the trigger forward for it to properly engage the hammer for the next cocking of the hammer.
This is true because the sole purpose of that longest second spring tine on the bolt/trigger spring, (the tine that is exclusively for the trigger), is to return the trigger to its forward position so its engagement surfaces are ready to engage the hammer when it cocks again. If only that one tine (that tensions the trigger) of the bolt/trigger spring were to break, you could still operate the revolver but you would manually have to return the trigger to its forward position as you cocked the revolver so that the trigger would again properly engage the hammer for the next shot.
Lessening the tension of the trigger return spring (bolt/trigger spring) so that it does not exert as much tension upon the bolt and therefore lessens cylinder ringing and peening....as long as that spring has enough tension to drop the bolt to the proper height, will be an inconsequentially tiny lessening of tension that you will not even notice the decrease of when you pull the trigger....because by that time you will already have taken the slack out of the trigger (bolt/trigger spring tension) before you actually pull it the rest of the way to fire the revolver.
In order to lessen tension upon the bolt, you have to lessen trigger return tension because the same spring operates both with its twin tines and one screw tensions down both tines of that spring. But lessening the trigger return tension will not adversely affect anything and by likewise lessening the tension upon your bolt so that it has no more than enough tension to drop to the proper height....you will decrease tensional wear of ringing and peening of your cylinder.
The FELT lessening of trigger return tension is inconsequential to what you feel with your finger....but it makes a big difference in lessening tension upon the bolt so that the bolt does not drop with more tension than is necessary. This difference in tension between the spring's trigger tine and its bolt tine is caused by the fact that the spring's tine that operates the bolt is much shorter than the tine that operates the trigger's forward return. By that spring's bolt tine being shorter it exerts much more tension upon the bolt than the spring's longer tine for the trigger exerts.
But since both tines of that spring are both tensioned down by one screw there is not a separate adjustment (would be cool if the tines could be separately tensioned and easier to make replacement springs too and you wouldn't have to replace the entire two tine spring if only one separate tine broke). So lessening tension on both of them by unscrewing the single screw holding the bolt/trigger spring....will affect the tension on the bolt's shorter spring tine much more than it will on the trigger's longer spring tine.So lessening the tension of the bolt/trigger spring retaining screw makes only a small difference in felt trigger return tension, but it makes a BIG difference in the tension exerted upon the bolt.
Trust me fellas. Give lessening your bolt/trigger spring tension a try. Like me you will notice that it decreases the degree of and prolongs the inevitable onslaught of ringing of your cylinders much longer and also decreases chances of peening by its lessened tension too. Plus the lessened tensional flexing of both your spring tines increases the spring's life.
It's a win win all the way.
