Machinists: Any useable threads on this?

Sure, the suppressor alignment is the shoulder or barrel front, not the threads. Just cleanup the threads and if the suppressor wants to come lose put a tiny amount of blue loctite on it. The dried loctite in the threads will help the resistance fit later.
KKM barrels used with compensator may not be a typical thread pitch and often have a set screw. Might want to double check thread if not sure.

Thanks for your reply! Just what I was looking for
From the picture it is hard to tell how much thread damage and how much threads full of thread locker. As long as threads get good bite you are good.
Glad you mentioned the thread pitch. Pretty sure they are 9/16x32. Which would be unusable for me since I can’t find a piston to fit that
There is probably enough meat to cut it down to 1/2-28. The min dia on 9/16 should be greater than .500. If lathe cut the flat spot should not matter, do not try a die, you need a square cut shoulder.
Assuming 9mm.

First off is the material just rolled over into the grooves or is the material sheared off?
Is it for a pistol or something longer? As in could it be shortened and re threaded?
Speaking from experience clocking an existing thread isn't easy. Also the threads were likely cut to a class 3 fit. That is a pitch diameter of 0.5422 - 0.5396. If you did a die it might overcut that.
You also wouldn't have the thread engagement for the first few threads so you would only be using the back few threads. Not the smartest to keep everything aligned.

Sorry, yes this is for 9mm. Kkm Glock 19 barrel
He’s out of state so I can’t see it visually but it looks like the material is all rolled over. I like the idea if it can be re threaded to 1/2x28. Only hesitancy is the cost to get it re cut. He would give me the barrel cheap, but if re cutting is pricey then I may pass on it. Any recommendations on who can do it?

I called Morgan over at class 3 machining. He said No problem to change it to 1/2x28. So going to go that route. Thanks for all the replies!!
KKM makes an outstanding barrel, I'm glad to see it get a second chance!
