Is this repairable ?

Done. Fetched it back today. I cannot be more satisfied. Scott did excellent job. Even the curved corner of the "L" was created. After some fitting work, it fits into the pistol and operates perfectly. He told me that his company has been doing micro-welding in other fields for years, now opened new service repairing gun parts.

I got a chance to look at a laser welder. It's pretty big. Looking into operator lens -- it's not unlike looking through a sniper rifle's scope, there is a cross inside, probably the intersection of those two thin lines is where laser beam goes

Here is the company provided the service:
