Thread problems - TRYBE Defense Glock 21 Match Grade Threaded Pistol Barrel

For those writing about issues with the threads on these barrels, I’m not sure if you’re aware or not but some Glock 21 barrels are threaded with a metric thread pitch which is 16x1 Left Hand threads. Meaning it screws on counter clockwise. Perhaps that’s the case with these barrels. There is absolutely now way a Glock 21 barrel is threaded in 1/2-28 because of the diameter of the barrel. I hope this helps. For the record, I do not own this barrel but in order to write this review I had to rate the product. Good Luck
