That’s totally understandable. For me, I know for a fact that my P10C has less than 300 rounds and has never been taken apart before until i purchased it. I’m a somewhat handy guy and dont “brute force” things, but i can confirm mine does in fact have those cracks, which ill try to post later on. Not saying it’s a wide spread issue or even something to worry about but i did get that sinking stomach feeling seeing a crack in the first place. Regardless, I love my P10C and dont think ill ever get rid of it, especially since im in CA and had to pay a bleep premium to even get it.
