I tell you. The more I shoot this shotgun, the more I absolutely love it! There most certainly was a break-in period. However, now that I'm on the other side, I've come to appreciate just how smooth and reliable the ARGO system is. A thorough cleaning and generous lube really helps, especially right out of the box. I'm pretty much shooting any ammo I wish, as fast as I want. I can't remember the last time it failed to cycle correctly. Slugs are accurate as any smooth bore I've shot. I am so happy I got this shotgun. Just thought I'd throw that out there.
