Greetings, I have a HiPoint 40 that I have only fired 42 rounds through. I have owned it since 2016, unfortunately I never cleaned it (first mistake). This year 2021 I went to the range to practice and when I got the firearm loaded and pulled the trigger nothing happened. The trigger is solid/ will not pull. I figured I would pull the slide off according to instructions. I put it back together and have the same issue, any suggestions? Also the trigger will not release the firing pin when the slide is charged with an empty magazine.
