Probably quite a few, the same thing seems to happen with countless other cheap guns.
Depends on what is meant by "cheap". If one meant reasonably priced, then, perhaps.
I can remember when Datsun, Volkswagon, Toyota, and Honda vehicles had that same appellation. They WERE considerably less expensive than comparable American Models, but that was all. The cars lasted, performed, and gave gas mileage that Detroit only fantasized about.
Today, cheap comes with an almost universal understanding of poor quality. That certainly isn't the case with the PT92.
FYI, the NSSF hired a firm recently, who interviewed 10,000 handgun owners about their reasons for owning a handgun, how many they own, and how many were bought new.
To some, 10,000 isn't a large number. However, political polls are often drawn from 10% that many on numerous subjects.
Funnily, 38% of the respondents owned Ruger, 33% owned S&W, 17% owned Glock, 15% owned Taurus, 14% owned Springfield, 13% owned Colt, 10% Sig Sauer, 9% Browning, and 7% Kimber. Other guns were in lesser percentages.
Funny how so many of our "experts" are so far off base with buyers actual results.
It also mentioned that less than 10% of handgun owners have a single gun. The results show that.
