My TRP had a glued in ejector too, I changed out all the MIM parts for forged/machine made ones. I had to use a propane torch to heat the ejector enough to soften the glue but it came out pretty easily.
Sounds like a good idea. Glued in is just a bad idea. I recall a few years ago in the Snap-On tool truch, they had a box of plastic pop rivets marked Pontiac body kit. Yep, you dent a quarter panel, they just install a new one using plastic pops. Gives one a great feeling about a collision.
About 15 years ago I had a customer's wife come to pick up a chimney cap + my dog at the time bit through the front bumper of her new F-150 P.U. She was pissed, understandably, so I didn't charge her for the cap but told her you should REALLY be concerned with a front bumper that a dog can bite through.
My TRP has/had a glued in ejector. I changed it to a Wilson bulletproof. I had to heat the old part to soften the glue, whatever kind it was. Used red locktite to hold the new part in place. I considered getting a gunsmith to drill the frame for the standard roll pin but decided the ejector can’t come out even if it’s not secured unless the slide is off the frame so I left it alone.
