Thank you, Sir.... The gun opens now kinda like a smooth hydraulic strut.
 I was not looking to get the loose, fall open of a competition SASS SXS.

Headed to a bit distant LGS and reconnoiter, main reason is hooking up with a friend for a BBQ lunch.
 He lives over in another county, and Sonny's is about halfway, the Gun shop is halfway of my travel.

My Ruger SR9 was furnished with a loader for double stack mags. I can't load a magazine without it.

I bought one for single stack mags on Amazon. Name on it is "Racine.com". It works for 9mm single stack and also works on the 1911 .45acp. Don't remember what I paid for it.

Thanks y’all for the explanation and pics/links to show exactly what you’re talking about.
So many fun guns. I’m
So thankful for Uberti and their importers for giving us a chance to shoot these great firearms.

   Oh Balderdash.  I als forgot, one needs to not the difference in the Barrel Lug.  The 1860 Richards/Mason has the "new" manufacture barrel with the "S" Lug while the 1860 type II Transitional reflects the use of the original 1860 Army pattern Percussion Barrel.

And then Along Came Jones!!

I've never owned a '60 R-M and have no pics of one.  But like Coffinmaker said, pics are on Cimarron's website.  Yes, the Richards (Type II, that is) has part of the ejector rod exposed.  It is the under barrel lug area that is different, as the Type II originally had a rammer attached, and the R-M was a new dedicated barrel for cartridges so didn't need that big hunk of metal underneath the barrel.  The R-M barrel is also similarly shaped to the Opentop barrel.

Note that the ejector rod is short in those pictures, barely longer than the ejector housing.  Those are old pictures.  Some originals were like that, including the one owned by Mike Harvey that was sent to Italy to copy.  But it makes it harder to eject empties, so they quickly changed to the full length rod.
