How many Benelli handguns have you seen? This is the Benelli B76 in 9mm and is one of the more obscure pistols I own. Fortunately, I found a really thorough rundown on it done by Ian of Forgotten Weapons. Apparently is was just in time to be made obsolescent by a certain Austrian upstart. It seems there were not many entities interested in a couple pounds of single stack, weird to field strip, steel service pistol.
Ian has an extended explanation in his video of why this operating system is "close to magic" in its true inertia delay system.
