Recently I bought Cometa and put around 1000-1100 pellets trough it. Gun is beautiful, accurate, light with crisp trigger. Unfortunately I have found some problems. First - screw on the trigger guard keep coming loos after 30 to 50 shots and its annoying, second screw on the trigger guard just keep on turning, never tightening anything(I find that this screw does not afect accuracy). Second - gun sometimes shoot incredibly smooth and than sometimes really harsh.
Should I replace the screw and change the piston seal and relube the gun? Any solution?

If the screw goes into the wood of the stock not much you can do if the hole is striped out other than a little glue and maybe a tooth pick to fill the hole and then reinstall the screw.
All of these low end guns will benefit from a good lube tune.

Thanks on advice.

I have a Cometa Fenix as well. I purchased Moly Paste and Euro lube from Air Rifle Headquarters, stripped my gun down, cleaned it thoroughly and gave it a light lube. This made a big difference in the cocking action and overall performance of the rifle. I used some blue threadlock on the stock screws, be very careful with these screws they are very soft and can be stripped easily if the screwdriver doesn't fit perfectly. I also had to polish the ends of the spring as they were very sharp and could mark the inside of the chamber.
I also find that my rifle likes pellets with smaller head diameters like JSB Exacts. You could try some plumber's tape on that loose screw to increase diameter and give it better hold.

A couple of washers might help it tighten on some threads that are not stripped.
