9mm 442 ?

[tomahawk223]

can smith and wesson fit a 9mm cylinder to a 442-2, is it even possible.

with the cost of .38 special and very limited availability and not wanting to spend money on a ruger I was thinking of this.

thanks

Sure it's possible, but I doubt you'll convince S&W to do it for you. There are other ways (not really as good) to do what you are trying to do. Buy yourself and extra 442 cylinder and send it and the gun to a reputable gunsmith who does this sort of work.

It Is possible, but the Factory will not do it. There are many reasons why, but the most important is that they do not have 9MM cylinders in stock.

There are several very good gunsmiths that will rechamber your existing cylinder to 9MM and machine it for moon clips

Quite a few of your fellow Forum members have had this type of conversion done

I always have Mark at Pinnacle High Performance do any of mine

Mark's work is exceptional and his pricing is reasonable

One could probably acquire a S&W 940 for about the same price as a 442 conversion.
I often carry a 940.

Question for all you folks here on the forum,

Since the 9mm is a non-rimmed auto loading cartridge, can you run 9mm in a revolver such as the "940" without the use of moon clips?

And does the guns cylinder have to be cut for moonclips?

What does the ejector star catch on when depressing the rod to eject spent casings?

A 38 rim has .301" for a extractor to grab on to for case extraction
The 9mm rim has .00155" for a extractor to grab on too.

Do you feel lucky ?

The 442 has an aluminum frame. I am not aware of the aluminum frames being used for any cartridges with much higher pressure than .38 special, which is about 20,000 PSI.

Most of the lightweight 9mm conversions I am familiar with use scandium j-frames that were designed for the 35,000 PSI of .357 magnum. These frames can be expected to have a good lifespan with the similar pressure of 9mm.

Pinnacle or tk custom will convert one for you.

Other than cost of ammo, in my opinion the 9mm in a small revolver is not a great idea. I had first hand experience with the Ruger counterpart.This is what I found:
Because the 9mm rests on its case mouth (it is rimless) you cannot put a good crimp on it,so, there is a tendency for the bullet to jump forward and can jam up the gun.
Secondly, the recoil of the 9mm is wicked because there is no locked breech to absorb recoil.
Third, you will need moon clips to eject spent cases. Just to name a few and that's not counting the cost of the conversion.
