The Itahca Mag 10 was an oversized, expensive and very heavy shotgun limited to three shots. The Roadblocker was a "Tactical" variant with IIRC a 22" bbl instead of a 26". A low gloss finish was standard.
Some of these were ammo sensitive, the piece had the rep of being a bit finicky. However, a bit of tweaking, including a longer forcing cone, gave an owner a reliable, soft shooting(For something pushing 2 oz of lead over the sound barrier) and durable auto that would reach a little further and hit a little harder than others.
IMO, a nice piece for those who want a 10.
