The same people have owned CGUSA from day one,Wes Lang and Guerini USA, they have built a very good brand in a down economy by providing a quality gun with features that US shooters want and excellent factory service and by service I don't just mean fixing a broken gun,for instance call with a question and if they can't answer it right away they make sure you are called back by the end of the day with the answer.
Between the 2 guns I chose the Guerini, my first Trap gun was a Joel Etchen combo, a very nice gun,3 things kind of bothered me, it loosened up pretty fast, the trigger was kind of loose and floppy and the top lever was always sticky. I decided to sell it and get a Guerini top single Trap gun. In comparison the Guerini has much better triggers that have not changed over 40k rounds or so, the gun has stayed tight,still requires it to be pushed open with a very precise feel to it.
I had 1 breakage at about 30k rounds or so,the part that broke had already been redesigned,broke it on Sunday winter league, called down on Monday, took it in on Tuesday, had it back in an hour, fixed and serviced,all for no charge
Over the last three years or so I have got to the point where I don't want any other Trap gun,I've tried others and I don't really see where I would do any better than with my Guerini. I plan to give their lifetime warranty a test.
I've since added a Impact and love it,shoot it for sporting clays and trap doubles,like it every bit as much as the Trap gun and if I had to could make it my everyday Trap gun,easily adjustable gun that moves very well. I'm not a doubles shooter and a couple years ago at the state shoot I had a chance for high overall,shot the Impact for doubles the first time,broke a 90 and won my overall class.It is an easy gun to shoot well.
