I used to dislike automatic transmissions, but ended up with a couple vehicles that had them due to being the only thing available when I needed a vehicle. I was glad when I broke my foot living 35 miles from town. Twice in 10 years. There were a couple other little mishaps that reinforced the appreciation for automatic transmissions.
The 1860 Henry rifle is interesting in historical context, but Ive never really wanted to own one. Ive seen a number of CAS folks mention having seen or experienced Henry mag mishaps.
One point he didnt mention about the 1866 is its basically impossible to do what he did because theres no way to pull the magazine follower all the way out then let it slam back. The other features mentioned were not really the main reason for safety improvement since thats not possible to do. Definitely improvements, just not really for the reasons mentioned. I confess to having a serious like for the 1866 carbines, I hope to lay hands on one again some day.
