Makes sense. I'm going to look into some little rubber thing I could put into the hole to save the hammer, too. I swear I have something that looks the part in the garage. Don't we always?
Looks like the pins are only 2-4 bucks, but why even risk damage to the ferrules, hammer, etc.
To date I've only ever loaded 6 rounds at a time, in front of me at the range, right before shooting. I've never done CAS before but am interested now and trying to figure out what makes sense— getting another 1858 and cylinder and going with that, or going with something simpler like a brace of '75s.
