I have a HI Point C9 Comp model with well over 2k rounds through it. Had some problems with light strikes around the 2k point, called the toll free number and got a new firing pin and springs, free, and in 3 days. Little heavier trigger pull now, but still eats whatever I throw in the mags. BUT... I take care of my guns, I clean them and if I see a way to make them more reliable I do it. Magazines are a huge issue with many semi-autos. The .40 JCP Hi Point I bought new worked great with the magazine that came with it. I bought four more mags, and NONE of them would feed reliably. I deburred the ears and set them to the same specs as the good mag and haven't had a problem with any of them since. Bought it new last year so it's only at around the 500 round mark at the moment.
Won't cc either of them, but not because of reliability, just that their striker is under full spring tension when a round is chambered and there is no striker block safety, so a sear failure would result in an accidental discharge.
I shoot a buddy's Phoenix Arms HP22 and am thinking about picking one up. Works fine as long as you shoot decent ammo in it. And Hartmen, just because you buy the ammo at Wallyworld doesn't mean it's crap ammo, just don't buy the cheapest they have, maybe see what yours carries, then google in online and pick one with a decent velocity.
