Will the trigger return springs on the old model and new model single actions interchange?

As Dave posted above, no. But with simple modifications new and old springs can be interchanged.

What did you have in mind?

The trigger spring and mounting are very different in the NM Grip Frame. However:

An OM trigger spring can be used in the new model GF with a simple adapter and a slight modification to the NM trigger. So NM GFs can be installed on old models.

OM GFs can be installed on NMs using the OM spring and again with a slight modification to the NM trigger.

I have an old model with a scary light trigger. I have several new model trigger return springs. Just want to add a pound or so to the old models trigger pull.

Thumbcocker.... best way to see what’s going on is to disassemble revolver. So-called “old model” Ruger single actions use a plunger loaded by a small coil spring to rebound the trigger. If the coil is rusty, weak, broken, or clogged, it may lack the strength and length to properly hold the trigger forward.

Another possibility, the SEAR TIP on the TRIGGER and be rounded, worn, or damaged. Or, the FULL COCK DOG on the hammer rounded, damaged, or improperly stoned.

Good time to strip clean the revolver, lube and reassemble. If the trigger spring is shot, replace it.

This one was worked over by a pistol Smith. Trigger breaks at 2 lbs. Work was done before I got it.

The trigger spring was possibly cut to get the 2 lb pull.

Examine both ends of the spring to confirm they match and on that one end hasn't been snipped. If so, replace the spring.

You can also confirm if a new one will solve the problem by putting a shim in the bottom of the spring hole in the grip frame to increase the spring tension and trigger pull.
