I can attest to how tough a double barrel is.. started off my work day by t-boning someone.
mod was in the cup holder and went flying, well.. everything went flying, even my glasses.. except me, of course (safety belt). Someone ran a red light, I had no chance at all. Luckily I hit her rear left passenger door, and not driver door. I would have seriously injured or killed her. She was uninjured, but very shaken up(as was I, not a great way to start your morning).. elderly woman. I'm glad I wasn't hurt at all, but adrenaline may be masking ailments. My double barrel and Erl also escaped damage. Maybe a scuff on the polycarbonate
tank, but nothing on the DB.
