Funny that the OP mentioned pinching his finger from his G26 bc as I type this I have a blood blister on the palm of my hand from reloading my P10C recently at an IDPA match.
I’ve had my P10C since late 2017, so it’s a Gen 1.5 or thereabouts. It didn’t have the striker plate hang-up issue that was present in some of the original Gen 1’s, but even so I installed a part from CGW that added a small rod from the striker to the striker plate to keep it from rotating and preventing the slide from going back into battery. I also replaced the striker with the tool steel one from CGW bc I’ve had MIM parts break (kept the OEM one as a backup in my parts kit). Also dropped in a HBi trigger and the lightened striker springs but after a few thousand rounds started to get lite strikes so went back to the OEM striker spring.
The P10C was also my first gun I added a red dot. This is pre-OR models being released so I had Jagerwerks mill it for an RMR and BUIS in front of the optic. Fun gun, shot it in USPSA CO division for about 6 months before going to the Shadow 2 as a dedicated comp gun, but carried it as my EDC for a while and also shot it in IDPA. Have about 7K rnds on it as of last counting.
As mentioned above, my palm overhangs the bottom of the grip a little and sometimes when I do a hasty reload I pinch the bottom of my palm between the mag and magwell.
Another issue I had was when using P10F mag (for higher capacity) it is possible to over insert the mag when the slide was locked back and hit the ejector. After a while the ejector got bent enough that it was hard to re-assemble the slide. So I replaced the sear cage housing which contains the ejector with the OEM part -easy enough to do. I don’t think it is possible to over-insert a standard P10C mag because of the way the basepads overhang the grip, but if you try to run P10F mags in a P10C (or P10C mags in a P10S) be warned that over-insertion is a possibility.
It’s a fun gun, one I don’t see a reason to get rid of. That said, when I got the 365XL that gun became my go-to EDC gun and I shoot the smaller 356XL just as well as the larger P10C. Capacity of 12+1 w/ a 15 rnd spare mag is good enough for me. And oddly enough, I’ve never pinched my palm doing a reload with the 365XL, despite it having a significantly shorter grip than the P10C.
