Only Double I own was my Maternal Grandfather's. Nothin Fancy, a Ranger 12ga SBS, Field Grade I believe, Double Triggers. First (& last) time I fired it, I discovered that no matter which trigger was pulled-Both Barrels discharged Simultaneously. Bout knocked me on my Wallet! So it'll stay in the Safe, for "Lookin at" & Memories only. RIP TTD (Passed after 93 yrs, burying 3 Wives, and BTW-Two Girlfriends attended his Funeral)
