Hi, and thanks in advance for any insight you may have. I recently picked up a P-10 S and it started throwing malfunctions right out of the box. It will go into slide lock randomly and has had some double feeds. The trigger will also go slack for seemingly no reason. I tried multiple mags and different ammo. My dealer tried sending it back to CZ (didn't buy the gun from him but he was trying to help out) and they sent it back saying i had to send it in myself. Tried calling them and no one ever picks up. Right now I'd rather not have a firearm out of action for who knows how long trying to send it back to them, so I'd rather fix it myself or take it to a gun smith. I already had one look at it and he couldn't figure out what the problem was. Has anyone had experience with a P-10 S doing this kind of thing? Thanks.
