Companies make inline changes all the time. The PX4, (or insert model here) you buy today may, or may not be the same as an example from 10 years ago.
Another factor is the PX4’s rotating barrel lock up requires a unique lubrication procedure for best results.
Having tried a couple of PX4, including a Langdon model I still hate them despite being a big 92 fan.
As for the P320, SIG has “fixed” the drop safety issue and the issue with magazines disassembling if dropped loaded or partially loaded. The new mags have a square, rather than round take down hole in the base pad.
The SIG P320 design, when properly executed, is safe, accurate and reliable.
Now, SIG continued selling non drop safe guns for more than 6 months after they knew about and had engineered a fix for the drop safe issue. It took a federal lawsuit for them to acknowledge there was a problem.
They also have both US and Italian made mags but only recommend the Italian mags for Duty use.
Thus the question is not has the design been corrected ? It has, but rather, do you trust SIG to execute it properly ?
