I am not sure what the coincidence would be. I own several P220 pistols in several different configurations and a Browning BDA .45. I have never had a problem with any of them. I don't own or shoot striker fire guns so I don't have any experience with the P320 or M17. I am currently on the hunt for a P210 long slide or P240 if you know someone needing to sell one.
While you hunt for a collector one, the USA production P210 with the 5" barrel is actually exceptionally well made, well fitted, very smooth and shoots well.
It's a nice one to have fun shooting with and then save the super expensive collectors one for special occasions.
The P226-XFive in USA production is another very well built, very well fitted, very smooth and well shooting option that you can use hard at the range and not feel guilty about. The adjustable trigger is really well thought out.
I have the M17 and M18 and they work well, but in the trigger department the H&K VP9 or the Walther PDP outclass them.
You can get the P320 with a better trigger, I've never spent the money to do so.
