I have a Tac Sport I picked up a couple of years ago. It is my primary pistol for USPSA and 3 Gun. About a month ago I had a hiccup on one stage at a local match. The gun ran flawlessly for the rest of the match so I didn't think anything of it. Fast forward a month and the problem is getting worse. I shot a 2 day match this past weekend and retired the pistol after the second stage. I had 3 malfunctions on the first stage and 5 on the second stage. There have been other matches in between with some malfunctions but the problem is now more pronounced.
Here is what is happening. After I fire a shot, the slide cycles, the hammer is cocked, a new round is chambered but the trigger is not resetting. The trigger feels dead when I try to pull it. I thought maybe I was riding the trigger and not letting it reset but this past weekend, on the clock, I made sure to remove my finger to allow the trigger to reset but it did not. The fix has been to manually rack another round and then it seems to work. I did have one malfunction last weekend were I had to rack it twice to get it running again.
I'm hoping the collective CZ knowledge of BE may have some insights on diagnosing the issue and potential fixes. I regularly clean the pistol (clean the barrel, remove carbon & oil/grease the slide). I will admit however that I rarely go much deeper than that when cleaning.
Thank you in advance for taking the time to read this and offering advice.
