Home made quick release lever from aluminum. Very fast cylinder changes. I'm not really into cowboy action shooting, this is fast becoming my favorite woods gun. With the 45 Colt cylinder, some ratshot for snakes, and cast bullets for bugger pests, this has become my go to pistol. It's a shame I can't share it on the 1858 Remington Forum (another site), but my application to join has been passed over twice, so I'm giving up on them. Enjoy!
