I got my Guerini in the Spring of 2009 and put 9,575 shells thru it that year. This year, I put 20,300 shells thru it. All without a single hiccup. I think they are great guns for the money and they seem to be catching on. Mine is going to their Maryland facility this winter for a checkup, for free.
I saw this picture on Trapshooters.com today, its a custom stock for a CG made by Dennis DeVault. Imagine how big the owner's hands must be to fit that grip.
