Dave,
Never heard of this combo, and I've heard both good & bad on Italian made guns, so it's hard to say. Does he have any paperwork you can check out, and perhaps find a website? Can you handle the gun to try to draw a conclusion? What is it comparable to pricewise? Is it expensive, or reasonable. If you can't get any info, I'd look the gun over carefully, check out the quality, you do have other combo guns to compare it to, and draw a conclusion from there, depending on the price. Sorry I can't help you more.
Sincerely,
Garry
