I haven't seen too many Gamba's around here neither in Washington state where I shoot NSCA tournaments. I knew 2 guys who were shooting them in BC. I think that European Arms had some parts for them. They are nice guns, but if they break, you may loose the gun for awhile. If you want to spend the money on a high end gun, I would definitely stick to guns that are more widespread and have good service and an easy access to parts. My honest opinion.
I concur!Gamba shotguns are like boutique hotels: just special!
