I have few Girsans.
They are great guns for the price--shot over 1000 rounds from my MC 28 and had absolutely zero malfunction or any issue.
I read old MC28 model had firing pin issue (if you dry fire a lot it might snap). Parts are almost impossible to find and that's one of the main cons of this gun (some basic M&P parts might be interchangeable)
I also bought the MC 9T but I think the recoil spring was a bit stiff and has failure to eject. It will need some breaking in.
