I was reading the November 1978 issue of the "American Rifleman" and saw a letter in the Dope Bag section. (I could not get it to post but will include a copy of the letter.)

.30 Carbine Revolver
I have been told that the u.s. Governmen once considered a handgun for the .30 MI carbine cartridge. If so, when did this happen and what were the circumstances.
Answer: At least one experiment of this nature is on record. The Record of Army Ordnance Research Vol. 1
Book 2 of January 1946 carried the following photograph and text which is self-explanatory:
"The Smith & Wesson Company developed a revolver to fire the car-bine cartridge and submitted this
weapon to the Ordnance Department for test in January 1944. The weapon weighed 42 ounces, unloaded.
"In test at Aberdeen Proving Ground, a total of 1,232 rounds were fired with no malfunctions or breakages.
The instrumental velocity obtained at 53 feet averaged 1,277 feet per second. A mean radius of 1.39
inches with an extreme spread of 4.18 inches was obtained by firing 10 targets of 10 shots each, at 25-yard
range, by a shooter using two hands, on a sand bag rest. The muzzle blast was very sharp and caused considerable
discomfort to the shooters without ear plugs. "Results of this test, together with the weapon, were presented to members
of Headquarters, Army Ground Forces, who stated that no military requirement existed for a weapon of that type."
In answer to an inquiry by the NRA Technical Staff, Mr. R. G. Jinks, the S&W historian, commented:
"Smith & Wesson produced a series of test revolvers in this caliber in late 1943. Several guns were submitted
for testing to the Aberdeen Proving Ground and some to the armory in Springfield. The experimental guns
were produced in both fixed and adjustable sights, and were designed to be used with cartridges and halfmoon
clips."
No other mention of .30 Carbine caliber handguns has yet been found in government records though, of
course, the cartridge has been successfully adapted to commercial handguns in recent years.-P.D.

They also included a picture of a 4" fixed sighted revolver which I now know is an "N" frame. I searched the forum and only found a couple of references in the archives. It is an interesting concept and makes me wonder if any got away from the Military and into private hands.

I have seen one, it is in a private collection. Extremely loud to fire by report. You'll probably have to settle for a Ruger Blackhawk if you want a factory revolver in this chambering ;).
 
That would be cool! I would love one to go along with my Blackhawk and my M1. The 30 Carbine Blackhawk is one of my favorite Rugers.
 
I saw one in a display a couple of years ago. I'm pretty sure that it was a longer barrel, probably 6 inches with adjustable sights. Anyway that is my remembrance. As I am mainly interested in N frames with adjustable sights, I doubt a 4 inch fixed sight gun would have attracted my eyes.
 
Saw many of the M-2 variation-with the selector switch-being used by truckers and convoy guys in Nam. All were sawed off, had 2-3 clips taped together-and were popular because you could employ them one handed and have a lot of fire power on hand very quickly. Just stick it out the window and spray.
 
I want to know how they got over 1,200 FPS from a 4" gun. I get only 1,100 from my 7.5" Ruger.

Obviously, it's +P! :p

I shudder to think just how much one of these would cost, given the scarcity. I think the Army was right - solution in search of a problem.
 
I thought I read somewhere that that .30 straight case round was initially designed as a handgun round. True?
 
No, the 30C was a rifle cartridge in design, but the rifle was intended to replace the handgun carried by some soldiers. But as compact and light as the M1 Carbine is, it's still way less convenient to carry than a pistol in a holster.

The case is reportedly based on the .32 Winchester Self-Loader rifle cartridge.

Regarding chambering the .30 Carbine in a revolver, it was probably a contingency project to see if the combination was feasible...in concept similar to chambering the .45 ACP in revolvers during WW I, which worked out well.
 
"The muzzle blast was very sharp and caused considerable
discomfort to the shooters without ear plugs."

I know what it sounds like from a Ruger Blackhawk, it would be ear shattering without ear protection.

30 carbine is one of the most unpleasant rounds I've ever fired from a revolver. All set with that :-)
 
Arcadia Machine & Tool (AMT) manufactured .30 Carbine stainless automatics stamped Automag. .22 WRM Automag IIs and .30 Carbine Automag IIIs were common at the local ranges I used during the 1980s. Their style followed other sizes of similar looking pistols chambered for 9 mm Win. Magnum, 10 mm IAI Magnum and .45 Win. Mag. Unfortunatly, I do not recall a single pistol from the series that was not a jam-o-matic.

I thought I read somewhere that that .30 straight case round was initially designed as a handgun round. True?

Although it was a smaller cartridge some place I read that the starting point for the concept of the .30 Carbine cartridge was the .30 Peterson cartridge used in the WW I simi-automatic insert for the 1903 Springfield. The insert was only intended to be fired while installed in a rifle but under modern law I believe it would be a pistol so an argument can be made that you are correct.

BTW, .30 Carbines were the most numerous small arm used by Uncle Sam during WW II.
