Possibility of the firing pin is/was stuck in the forward position?? You may have had a slam fire, which has out of battery detonation tendency. Look at the bolt head and see if firing pin is slightly sticking proud of the bolt face. Strip the bolt down, give a good cleaning and lube as required.
More than likely the Trigger bar has been polished and tweeked. The "cruxiform" portion that trips the striker sounds like it has been flattened down some.
I would reach out to Rudy with Macon Armory and see if he can help out.

@workky Take a look at the muzzle end (please make sure it is unloaded first) and compare with both barrels installed, completely assembled and on the frame. I am betting that the SilencerCo barrel will have a little more gap at the top than the bottom (see picture). Sounds like the barrel lug...
Also, your barrel maybe a Type 1 which will be a depth of .125 and your bolt maybe a Type 2 which is .136 depth of the lugs.
You need to confirm what your barrel is and that your bolt matches up to the same specs. I believe the Odin Works is a Type 2, which is preferred.
Try calling them and asking if they can send some your way. Or look for a Certified Glock Armorer in your area.
Just a few options or you can look online at websites like Lone Wolf or Glockmeister.com if it is still up and running.
Be cheaper to buy one already that size and already threaded. Swap them out and sell the older one. Might make your money back to break even.
Or just go to Dobbs like everyone else said.
