Thank you so much for sending me a frame. Unfortunately it won't work without major milling or fitting. Well it was worth a shot. I may just send the gun off to Ruger with the XRN-3Red AND the XR3 red you mailed me. They can sort it out. If I have to pay some money, that's fine.
Egads! It will be "some money"; very close to $200; over $100 just shipping it there and back!
Just buy this correct XRN-3Red grip frame:

OR:
This parts kit; you can resell the cylinder by itself for ~ $75:

OR:
The XR3-RED frame is an old model Ruger grip frame, pre 1973. Don't need to modify the grip frame. Just get this $2.00 plunger pin (below), install it with a ball point pen spring cut to length, in the trigger return spring hole behind the trigger, and slice off the shelf on the back of the trigger for new model return spring (no longer needed).
Drill the small hole in the top of the trigger guard for the cyl bolt plunger/spring. With a Dremel tool grind the trigger slot wider to fit the NM wide trigger, and you're back in business!
