Keep in mind that Remies have about 30 yrs. R&D on the Colt open top.
In defense of the o.t., once the arbor problem is corrected (Pietta seems to be getting a handle on this), a simple cap post will render cap jams a thing of the past. Unlike Remies, you will be able to shoot 100+ rounds with no cylinder binding (try that with a Remie). I know, I know . . . . you can have a bushing put in which will clear that problem up.
But, speaking of caps flying off, if you'll watch the video of brushhippie fanning his '51 (you can see it on my website), he shows it again in slow motion at the end and you can see the caps flying to the side.
