Would you sell it and buy something with available spare parts?
Or would you keep it "just because" as a potential gift for relatives or a beater?
Does it have historic value? Does it have sentimental value? (Turkish gun, probably no to either.) Does it have a place in your arsenal -- a purpose, a niche that it fills?
If the answer to these questions is "no", I'd trade it off or sell it, and buy something else.
