How about a .40 cal. J frame?

I haven't pulled out a micrometer to check the diameter on a J-frame cylinder, but my guess would be there isn't enough meat in one to leave proper exterior chamber walls if you open the charge holes up to .40" (or even more, since the base diameter on the .40 S&W case is .424").

Man, have you ever even looked at a J-frame barrel? Outside diameter of the threads is .5" . . . 
Why not??....My question is..... why?

I'm with Olda on this.
The .357 is a more potent cartridge than the .40 and it is already available.

Well, first you have to make the barrel bigger, then it won't fit the frame and you have to make the frame bigger, and guess what? You'd have an L frame!
If you make a J frame or K frame large enough to make a .40 caliber (that won't come apart), it would be the size of an L frame!
Same reason you can't put a gallon of milk into one quart bottle.

I thought they made one at one point? or was that one of the L frame ones?
something called the 640 I think, I looked into it once, 5 shot, looked kind of like my model 49 except stainless, maybe more along the lines of one of the centenal ones.
hell technically isnt the nightguard 10mm tecnically about the same size as J frame roughly?

the problem that I see is that it is such a high pressured round that if you did keep the gun from blowing apart, it would be a nightmare to shoot. Even in most polymer frames it has a lot of barrel flip, I can't imagine that in an airweight snubby.

L-frame, 6-shot, 646. The 640 is a 5-shot .38 Special or .357.
Sure you don't mean the .44 Special 296 with a silver-colored Airlite Ti setup?
Not even close; that's an N-frame.
Thanks for playing.
yep, read a writeup on it recently in a magazine....i think it was Combat Handguns

Sorry it wasnt a .40, it was actually a 9mm
the smith 940/547
I had looked into it because of the fact that 9mm has more velocity than .38 special plus with the rugers they made a cylinder for the 357's in 9mm which my dad actually has with his pre transfer bar 357.
plus 9mm is a great deal more common that .38 special and charter arms still makes one in 9mm.

I just sold a .40 646. It REALLY got your attention at the range. Couldn't imagine that in a J frame.

It won't be a J-frame.
