Geo,
The trap specific version of the Companion was sold alongside a much more expensive non folding Beretta trap gun, in the 1970s. I've seen and handled a few examples of each, and, I can assure you, the Companions in trap configuration got the hell shot out of them.
They showed no sign of being loose.
My Companion has a very specific purpose in life. I use it for snowshoe grouse hunting. The longish barrel makes it a pretty effective balance beam, and by the time I get it into firing position after a grouse has left a snow cave from between the tips of my snowshoes, I'm really happy I had a five pounds and change single shot along for the walk.
Did I mention the grouse is usually long gone at that point?
I figure if you aren't going to shoot a gun, have the lightest one in the safe with you.


Best,
Ted
