Whoa stop! First off you can safely adjust the trigger at home so long as you keep a firm grip on the barrel to stop it flying up
unless you don't know what your doing and you end up with a rifle that will fire without warning when cocked & loaded. this isn't a 'safe' home adjustment if you end up with a rifle that will either slam fire or if you get sear failures for whatever reason.
I will simply say from personal experience... if your not sure, don't risk it for the sake of you and those around you.
that said, if you do know what your doing - tinkering with old / cheap air rifles is a cracking hobby. I made a qb78 into an electric trigger bullpup for a giggle & it was a nice accurate gun out to 30 odd yards, admittedly not as accurate as the rapid or fenman but it wasn't bad!
