CZ P10c “Doubling”?

[GJM]

I spoke at length with their tech guy, yes.
His take was the trigger couldn’t cause the pistol to double, which I agree with.
After a trip to the range this AM the gun still doubles when shooting at speed.
I tried that slide on another lower with no issues.
The lower is the issue.

Closer examination at home has me believing the problem is the disconnector sticking and failing to click back into place after firing.
I took the entire assembly apart, examined components, cleaned and reassembled.
It APPEARS to be functioning properly now.
I’ll make another trip to the range tomorrow to function test.

I have learned a lot more about the P10c than I wanted to frankly.

What trigger is in the other lower?

^^ Same, HB Ind.

I figured this out.

The disconnector was sporadically hanging up inside the frame rail not ("popping out") allowing the gun to double.
I completely disassembled the trigger bar/disconnect, cleaned, lubed and reassembled. Visually it appeared fine after this (perhaps a burr/debris preventing tiny disconnect coil spring from functioning).
Ran out to the range and dumped 4, 17 rd. mags- no further issue with doubling.

I realize CZ would've taken care of this, but figured it would be simpler/quicker to just sort it out myself.
