I lived there for 20 years until I retired 18 months ago.

Gunsmiths are so few there. The old good ones were mostly rifle shotgun and have departed the planet. I do not know of any pistol smiths there.

Go to the yellow pages, look for gun smiths, call and ask who might work on pistols. Then I look at their work before I let them touch anything. I think you may have to send it out of town.

P.S. What is the brand and issue with your pistol?
