I can't find OEM threaded barrel for Gen5 G17 anywhere.

Therefore, I'm tempted to just go for cheap threaded barrels. Like these:

https://aimsurplus.com/products/aimsurplus-threaded-barrel-for-gen-5-glock-17-copper

Anyone have experience with these cheap options? Or if you can find an OEM threaded barrel somewhere, point me to it, please.
