Can you get the trigger to reset if you pull the trigger and then thump the butt of the gun on the floor to simulate recoil? Given that we're now into colder weather and that you were shooting clay targets, I'm wondering whether maybe a combination of heavier than normal clothing and loads lighter than you'd use when hunting ducks means that the trigger isn't getting enough of a recoil bump to make it work. Or did you try the gun with heavier hunting loads to see if that makes a difference?
No, nothing will reset it except moving the barrel selector. Bumping it on the floor was the first thing I tried, but no luck with that. I then fired a couple of 3" turkey shells, but it didn't help.
Hopefully it can get repaired in time for my hunt, but I'm also now hopeful that it will be a DT gun before next season.
Thanks for all the replies. I'll report back on what happens.
