I'm with @JCN on this one.
I drank the Px4 cool aide in 2018/2019 and acquired a full size version. I did the G conversion (decock only), installed a LTT trigger job in a bag, put on new sights (which are bitch to change, by the way), bought mags and holsters and put 1500 rounds through it, including a 2-day class with Ernest. (The class was excellent).
At the end of that experiment, I dusted off my old Gen 3 G19 and realized it was a far superior pistol, that I am capable of shooting much better. The Px4 went down the road shortly thereafter.
On the upside, my log book shows zero malfunctions with the Px4. But in a world of excellent pistols, the Px series are meh. I'm all-in on glocks, but f I had to carry a TDA pistol, it would probably be a HK P2000 worked over by LTT.
