I know this is a silly question, so if it doesn't get any answers, I won't be bothered. But the long thread about 41 Special has got me wondering: Would it be possible for the S&W L-frame to be a 6 shot revolver chambered for 10mm cartridge? Ignoring the problem of extraction and ejection?

My take on the 41 Special is that there is no point in basing a cartridge on a cut-down 41 Magnum, because the 41 Magnum is not popular enough to for such a cartridge to have significant sales. To me, if you want a short 40 caliber pistol cartridge, well, there already is one: 40 S&W.

The problem is, there is not a lot of point to a 40 S&W revolver, because there are already compact 40 S&W automatics out there that hold more than 6 shots, are flatter, can be fired more rapidly, and can be reloaded faster than a revolver.

But if a medium frame revolver could be made in 10mm, you might have what the 41 Special folks want: a caliber larger than 357, with better stopping power than 38 Special, but less flash, blast, and recoil than 357. And the 10mm option would offer even more power...which is what people always seem to want.

And it would address the felt need for the 41 Special using two existing cartridges, one of which is quite popular, instead of with one hypothetical cartridge and one marginally popular one.

I know that this has already been done with the S&W 610, but that was an N-frame, IIRC. And why would you want a 10mm revolver if, for the same size and weight, you could get one in 44 Magnum, 41 Magnum, 45 Long Colt, or 45ACP, all of which are N-frame options? Going down to the L-frame would give 40S&W / 10mm something to offer...if it is possible.**

** And now, after all this scribbling, it occurs to me that if it was possible, S&W would probably have done it instead of building the 610 on the N-frame. The other problem is that people never seem to like revolvers chambered for rimless auto-pistol cartridges. Well, it sounded good, for a minute there anyway. :)
 
There is one custom shop that will convert a GP100 to 10mm.

S&W built some L frame .40 revolvers.
Would they do ok if rechambered to 10mm? I don't know, the maximum pressure is only 7% higher but those titanium cylinders are their own thing.
 
A year ago, I would have said no.

Then they came out with the L-Frame .44 Magnum Model 69 last year.

So yes, there could be an L-Frame 10mm too.

But, it would have to be a 5-shot cylinder like the Model 69 in order to move the locking bolt cuts between the chambers.

That makes for a much stronger cylinder then it could possibly be in a 6-shot.

Unfortunately, going to a 5-shot cylinder would give the advantage to 357 Magnum (or 44, for that matter) and make the whole idea a non-starter.

Or is there already a 7-shot 357 Magnum L-frame? Or was that an N-frame? Smith & Wesson introduces so many guns that I cannot keep up.
 
Well in that case, how about a K-frame sized 10mm five shooter?

Or, just get a Charter Arms Bulldog in .44 special for the best power/size/weight ratio of any revolver made. :cool:

But yeah, I believe a firm did or still does a 10mm conversion for the Ruger GP100s, which are inherently tough numbers of a wheelgun to begin with.
 
Thanks! I had never heard of the GP-100 10mm conversion until now. (I have no idea why I assumed the S&W L-frame would have to be the starting point.) Good to know that some other people have had the same idea!

Since 41 Special can and has been done in a 357 Ruger GP100 six shot platform, the slightly smaller diameter .40 S&W might work too without the high pressure concerns of where the cylinder notches are located.
