I recently bought a Swenson cut slide for my Glock 19. I swapped out the barrel from my OEM slide and found that I was going to need to fo some milling due to the slide locking up when going into battery. I then purchased this March grade barrel and put it into the new slide and it runs like a charm. 300 rounds with zero issues. The thread protector is also high quality. Very happy
