Why not just open carry on the trail and not worry about polymer versus steel frame. I have fired one and the damn thing is a literal hand cannon. I personally would've felt more comfortable with a steel frame version, or even better a S&W governor.
But what does anyone's opinion on here mean to you, you're just gonna do whatever and when it doesn't work, complain! Haha. Besides, have you seen a snake yet out there? I have only seen one that was 12" long in all the trips I've been, and I would've been able to grab my single shot .410 if needed.
Basically, buy a truly concealable weapon and then buy your "snake handler" haha
