Thanks but like Donald, not really an expert, just a nosy enthusiast haha; but I do like to keep guns and shooters going as much and as long as possible. Have to say this forum is great for doing just that, always people willing to help, advice for one person often benefits many others and I'm glad I'm part of that.
Again I have to say many thanks for the help given, gun now working fine, parts a bit pricey though, but you can't do without them.
If anyone needs help on this trigger I think we have sorted most of the problems and the one I had was certainly not standard, but as this was my first Omega, I was certainly confused by the layout and it just goes to show not all tuned guns are better than standard ones; and I have to say it's a bit worrying that a supposedly improved gun was in fact so dangerous. Also it showed up several variations of trigger assy's. which is always a help to first time service / repair enthusiasts.
Big pat on the back guys.
So have a Merry Xmas and Good New Year everyone; and lets continue 2019 as we end 2018
