Uh, negative on the trigger guard thingy there, Lagopus. This has an underlever forward of the triggerguard that is pulled back to cock and open the gun. There is a half-moon section of wood hogged out in the forend to allow the gun to fold.
The best thing is it is a quality, hammerless, single, a tough thing to find in the US market, dominated by real junk 'ala the Winchester hammer 840 built in Canada.
It is not an especially attractive gun. But, it works quite well. They were available in all gauges, including 28 and 16 (there is a 16 on Gunbroker now, just go to single shots and search "Companion"). Not sure why someone would want a .410.
Best,
Ted
