9 mm is a tapered case, it does not do well in a 6 gunn

It does fair if you specifically make the cylinder for it.

A friend on mine's dad had an old Ruger Blackhawk convertible with two cylinders. The standard cylinder was .357/.38spl.....the spare cylinder was drilled for 9mm.

FOr mild loads its no big deal, what happens is it gets pushed back and can lock up the cylinder.  I bet accuracy was not that great since 9mm is .355"    does not sound like much but .002" is huge when it comes to guns.

As I recall, he did not shoot the 9mm in it very much because it was not as accurate.

If the bore was bored specifically for the 9mm, then moon clips in a DA might help with the potential lock-up you mention.

The big thing for a company to factor in is overall demand and whether it would sell enough units to be profitable with mass production over limited editions or customs.

Actually it is desirable for a revolver round to be pushed back against the breech face during the firing sequence.   If it doesn't then the primer will be pushed back and that will jam up the cylinder.  You can test this by firing cases with just primers: No bullets, no wads.  The primer will back out and drag on the breech face, making it difficult to turn the cylinder.  Two or more of these will lock up a gun. 

The whole firing sequence is a delicate ballet with the firing pin driving the round flush with the cylinder then as the case expands the round is driven back into the breech face, keeping the primer in the pocket and providing support for the whole case.  Hopefully the case expansion doesn't have too tight a grip on the chamber walls until the case head is fully supported by the breech, else the case head will rip off.  Then as the pressure subsides,  the case contracts some and the case is free to move back towards the cylinder thus freeing the cylinder to turn again.

The negative with a tapered case is that as the case goes backwards (desirable), the case expands into the larger diameter area and isn't able to contract back enough to move back into the cylinder (undesirable).  This can be alleviated in a revolver by have a slightly over sized forward half of the chamber -- ever so slightly over size.  But of course, the chamber must still engage the case mouth since on a rimless round (9mm) the headspace is the distance from the breech to the case mouth.

What Kevin and I want for shot 2014 is to go as a guest of SG to give a zero-to-hero view point of the new offerings.

I'll be going to the Monday Afternoon Range Day scrum, and Remington was just added to the list of exhibitors I want, nay, NEED to visit.

I wonder who makes it? 

[ExurbanKevin]

The R51? I'm guessing Para-USA makes it, they're the pistol part of Freedom Group these days.
