One of my favorite TGS episodes with Jonny was his in depth discussion of the Beretta 680 and progeny series. With a Leatherman tool, he stripped it down completely with commentary that parts availability is readily accessible, inexpensive, with no fitting required. The genius of the replaceable trunnions, ejector assembly, etc. was demonstrated. Well worth watching for those considering the series or owners who seek affirmation of their choice. Gil
