Smith & Wesson 686 and 9x19mm ammo

In short: no

Winblows

If you're thinking about shooting 9mm. in a .357 Magnum/.38 Special revolver you might want to check out Taurus's Model 692 Series. They come in blued and stainless with 4" and 6" barrel models.

How would the 9x19 headspace or eject? The above answer is the correct short version.

While the bore is nominally correct for the 9x19 bullet (not the case) it just wouldn't be truly practical without another cylinder. Even then moonclips are always a good idea for autoloader rounds going into revolver chambers and finding some for the 686 would be difficult at best.

If your deadset on it. You may want to get another revolver chambered in 9mm exactly. You can get a cylinder cut for moon clips though.

Nope, you cant do it. Then gun would easily handle the pressure but 9mm rounds wont fit in the cylinder. The 9mm case is tapered. Up at the bullet end its a couple thousands smaller but it gets bigger the further down the case you go. By the time you get a 9mm round about 3/4 the way into a charge hole it has become to fat to go further.
I just tried it in my 686 and you can see how much of the brass is sticking out. Way too much to close the cylinder. Moon clips wont even make this work

Oh pshaw, just stick 'em in a lathe and get'r done.

I'm kidding, of course. There are revolvers chambered in 9x19 if you're dead-set on ammo compatibility.

If you have wads of cash laying around, you can always acquire a Phillip & Rodgers M47 "Medusa". It's like Mikey and will eat anything (.38 special, .357 magnum, 9mm, .380acp, .38 super, you name it).
There's one on Gunbroker right now for only $9k

Korth announced a conversion kit a couple of years ago, but I don’t know if it ever came to fruition. Their revolvers are very pricey so I suspect the kit would be as well.

TK customs will rechamber the cylinder to 9mm, but warns you may bulge 38/357 brass and have rough extraction/ blown cases.

No, chamber size and heafspacing are different between the two cartridges.

Revolvers exist with interchangeable cylinders to accommodate both cartridges.

That warning is only for 9mm +P and super hot 357 Mag. As long as you stay under ~35,000 psi you very likely won't have an issue.



The above image is a screen crab from my CAD showing the profile of a SAAMI min spec 9x19mm chamber in blue overlaid with a min spec 357 Mag chamber. As you can see it is only the base of the 9mm cartridge that is bigger in diameter than the 357 Mag.

It does make the revolver even more ammo flexible though most people doing this conversion are doing it for competition where they are more concerned with using robust moonclips on short 9mm for fast reloads then pushing the velocity with really hot loads.

I thought of that.
I wonder if TK or Pinnacle can do business with Denmark.
It's only the cylinder going Transatlantic.

9mm won't work as everybody mentions, but if you could get some of the very thin moon clips that Taurus makes for their .380 revolver I bet you could shoot .380. But why anybody would bother is beyond me.

But even if it worked, it would not give the OP common ammo Glock to Smith.

True that. Just the only thing I could come up with. Close, but no cigar!

What some have done is buy the SW 627 which is an 8 shot .357 already cut for moon clips. Then they load rounds using the .38 short colt case. This gives a short package for quick ejection, in an unmodified revolver.

Personally, I went with the 929 in 9mm. Because of the slight taper it would seem even easier ejection.

Nope I don't think that will work.

I think if you google the subject, you'll find that just the opposite is true.

They are easier to insert into the chambers, but tend to "cling" more than straight walled cases. 8 cases "clinging" tend to cause the ejector star to "hang up a bit"

I believe this is as much, if not more, to do with the fact that S&W used a Titanium cylinder in the 929 as it with the tapered 9mm cases. Titanium is light and strong for its weight but it not the best material for releasing brass. There are issue with straight wall cartridges (38/357, 40, etc) sticking in titanium cylinders. The oxide finish on the Titanium can be a finicky thing to get right. That said if you can beat the case sticking problem the 9mm revolvers use thicker more robust moonclips that are far less finicky about brass than the 38/357 guns.

Is Apex doing any gunsmithing these days? All I see is a parts business.
So how is one to get an Apex TSW?

I really like the work Apex Tactical is doing with the .356 TSW cartridge. Randy says that the cases just fall out when he lifts the muzzle

Not sure that really does the revolver shooter much good? .356 TSW was made for Major power factor in an semi-auto Open gun. It is still a tapered case with nearly as much taper as 9mm. A USPSA 8-shot Revolver shooter is always scored Minor so there is no need for the super high pressure that cartridge was built for. You can make Minor power factor from a 6.5-inch 929 with relatively lightly loading 9mm ammo. Stepping away from the competition aspect. 357 Magnum out performs the .356 TSW in the energy/velocity department, especially with heavy for caliber bullets. The .356 TSW made some competition sense in a semi-auto but I am not seeing any advantage it offers over more common cartridges in a revolver.

The Ruger Blackhawk can be purchased with two cylinders, 357 and 9mm. Mine shoots both pretty well.
