45 Dragoon, you are the only one I know who shoots heavy loads in opentop designs.

But point taken.
Buckaroo, for your further reading pleasure:
https://www.cascity.com/forumhall/index.php?topic=63466.0I think it was Coffinmaker who came up with the "quick fix" of the split washer. On some of mine, that washer is too big and I use a thinner one. And as mentioned, some newer Ubertis have been reported by myself and others to not need the washer. Easy to check it to find out. Pettifogger's method in the articles of checking to see if it is too short doesn't work on my guns, the barrel assembly won't fit on all the way when turned sideways. But you can just drop something small down the arbor hole and try to seat the barrel to check it as well. I shot some of mine for 20 years before doing this, so it's not quite as "critical" as some would have you believe, though mine did probably wear a little more without it.
