The Ejector is a un-sprung rod that is held in check by a notch in the loading lever.
otherwise as you sermonize the lever holds the Cylinder pin in as in the C&B.
I have one in 45 Colt ,and it is a tack driver with Black Hills ammo.
but I also have several Colts and personally like these better for BP, they'll digest BP all match long.
The Colts include a 2nd Gen 1860 with a R&D drop in, a 51 Navy with a Kirst Gated conversion.
a Kenny Howell type 1 Richards 44 , a Type II Richards 44, a Richards & Mason 38 and an Open Top in 44.
