I've got the 12 ga in Marinecoat. (Old guy, old joke-it's fully protected against cranberry juice. Marinecoat protects from the Ocean Spray!) I have the Opsol thing, but haven't found shells yet. I discovered today they're making the Shockwave in in 410 (more like a Shockripple). Might be a good thing with the long buckshot rounds. Make a good companion to a Judge.
