i had my 800x for about 5 months now.. i shot about 30 shots today and then when i reloaded it it didnt work. when i break the barrell down it pushes right back up. i opened the gun up and i didnt find anything broken or out of place.. does any one have any suggesstions to how to fix this. if you do it will be greatly appreciated.

Check (1) that the sear is intact, (2) that the spring that pushes the sear up is in place (on my Brazilian model, it is VERY difficult to fit when I take it out, so good luck!), and that (3) you have not adjusted the trigger screw too much (this applies to the triggers with the adjustable screw; mine does not have that)
