A friend of mine brings one of these to range trips abd I have put over 500 rounds through it without issue. I know that he has too. Less experienced people have a number of cycling issues with the same gun because they anticipate (the almost non-existent) recoil and shake it like a rattle. My two cents is that, not specific to anything reported here, many of the reports with issues on this gun were from inexperienced folks who are now a larger % of gun owners.
