9mm/.357 DA revolver

[urbaneruralite]

Has anyone ever made a .357/9mm convertible double action revolver?

Medusa Model 47 was a short lived multi-caliber double action revolver.
The single action Ruger Blackhawk convertible is a lot more common.
That's it, AFAIK.

The bore size is not convertible. Do the 9s rattle their way through?

That .002" difference in bore really doesn't mean much in the real world, the 9mm bullets won't fall through the barrel, they engage the rifling and spin just fine. I have a S&W 360J that was rechambered to 9mm several years ago, no appreciable loss in accuracy using 9mm ammo vs .38spl.

I've seen some single action like the Vaquero and Blackawk in 9mm and .357 convertible, but not double actions, save the Medusa.

I'd like to see one myself.

Did some clicking. The FN Barracuda was the one I found. It has two cylinders. It seems there is a need for two cylinders due to the difference in shape between .38/.357 cartridge and the 9mm. .38s will fire in a chamber modified for 9mm, but will supposedly stick.

I did see where one customizer advertises a similar conversion to a .45LC as working fine with .45 ACP; no extra cylinder required.

I imagine when the powder ignights the force will cause the bullet to change shape and bulge a little from pressure and heat 356 to 357 should not matter.

The Manurhin MR73 target model in 6" barrel was offered with an optional 9mm cylinder to complement the 357 one. The extractor was similar to the Smith design used on the 547 in that it handles 9 mm rimless cartridges just fine without the use of moon clips. Somewhat rare to find but one glorious piece of steel. I've experienced no problems with the accuracy of the 9mm in this gun.

Load a revolver with 125 Golden Sabers and you have essentially the equivalent of the standard 124 grain 9mm loading. Other manufacturers may offer similar loads, check around.

It's been done a few times. The FN Barracuda that urbaneruralite mentions was actually made by Astra, who also sold it under their own name. The Astra version, at least, was offered in the US by Interarms.

Korth of Germany also made a convertible, but it cost an enormous amount of money, like all Korth pistols.

Anybody know if Ruger made any 9mm/357s like this for the French?

I've got a nickle smith 19 cylinder I'm thinking of having cut for 9mm moon clips to drop in my blued 19-3 and keeping the factory cylinder to revert to stock should i feel like it.

any reasons this might be a bad idea? Or any suggestions where i might send it to for machining? I was thinking cylinder and slide And having them do an action job as well. Would make for a heckuva conversation piece!

As I understand it, the 9mm Parabellum cartridge case is tapered, while the 38 Special /357 Magnum case is straight. I think that is why 9mm/357 convertible guns always come with two separate cylinders, except for some oddballs like the Medusa revolver that Radagast mentioned.
