My first gun was a mechanical trigger vl triad and it was cheap & good ,rarely chopped, reliable , but for a first gun I would have to suggest a spider , they don't have reliability problems and parts are easy to find . I went with the jt because I got it cheap ( cheap was not good in this instance )
If you can return your gun for a refund , do it ! or if your dealer will credit you towards a better marker . Playing with a marker that dosen't work half way through a game ruins your day fast.
