S&W 929 chambered in 9x21?

Recommended Posts

Looking at another forum it seems the S&W 929 is chambered in 9x21 not 9x19 (Luger)

Anyone could check and confirm this?

Here guns in 9x19 are forbidden while 9x21 is allowed, making possible to import such a beautiful revo

The cartridge is stamped on the barrel.  Whatever that says.

The barrel is stamped "9mm." In the US that's how we refer to 9x19.

I guess it would depend on your local laws.

I know the barrel and the box are marked "9mm", but owners of that revo found that 9x19 shoot ONLY if moonclipped.

9x21 rounds worked both with or without moonclips.

Would like to hear from other owners of that revo

Moon clips make extracting the empties in a revolver using rimless cartridges a lot easier. Come to think of it, loading is easier also.

My chambers are cut deeper than 9x19, you cannot fire a round if a cartridge is seated to full depth.

One of my 929's will allow the cylinder to spin when closed  loaded with 9X21 in moon clips ...the other will not.

In general S&W has a lot of excess tolerances in their 929.  (don't know a better way of putting it).

Many revolvers won't reliable fire 9MM rounds in moon clips as the gun comes from the factory.

Could be Cylinder, cylinder placement in the frame, firing pin length and on and on.

It's going to be a while before dimensions get tightened up if ever.

People keep saying this, that the guns won't run and won't extract. I would love to buy any of these guns if people want to get rid of them. It's an ammo issue, not a gun issue. The 929 is the same quality as the 627s. Things are wrong, but it's no better or worse than before. 

 

To the OP, if it doesn't specifically say 9x19 can't you import it as a 9x21? Worst case you put a finish reamer through it to make sure it's 9x21?

Based on MWPs comment I'd like to clarify that my gun fires 100% WITH moonclips.  Only when you are shooting loose rounds WITHOUT a moonclip does it fail to fire.  Also, my 929 was on the tight side tolerance wise and had properly sized throats and barrel.  It shoots well out to 100yds with standard .355 and .356 coated bullets.  I'm buying a second one soon.

I'm with you my 929 runs flawlessly and varry tight groups at 25 yards with my 160 grain bullets, and they are sized at .356

lol what? I've never heard of any of this. I mean at least concerning the 929s. I've seen all matter of S&W revos come in with barrels not torqued all the way center and burrs on the single action notch in the hammer, but never that guns wouldn't fire.

Many 929 owners have sent revolvers back to factory to get them to fire on all 8 rounds.

Many have sent them to gunsmiths after S&W failed to fix the problems.

I guess I am lucky.  I have two 929s and both have run excellent.  The factory trigger was terrible, but other than that, flawless.

I've seen it too. watched a guy bring a brand new 929 to a steel match and it would not make it through a full cylinder right out of the box. 

 

I get asked about revos regularly and this is what I tell people.

Smith sells a nice revolver kit, they put all the pieces in a box and they happen to assemble them,  but it is basically a kit that you will need to work on.

MWP , that is exactly what I'd like to do: import it as chambered in 9mm x 21mm or import only the cylinder

Factory 9mm don't remember the brand
If it was Winchester white box you can't blame the gun.

I think for some reason we are looking at a 929 like a production gun. It's not, it's a specialist gun, from a production line. Open guns probably won't work 100% with factory ammo, same with 40cal limited guns, they prefer long ammo. It's the same thing for the 929, it's not an out of the box ammo kind of gun.

We're looking at a commercial production gun with tolerance issues.

My observation/ impression as well which is why I'm learning to hand load before I get one. As for the "tuning," I have a guy...

I've seen this too, but it's always been the guy has tried to "tune" his revolver by just backing off the strain screw, resulting in light strikes on factory ammo. If you are going to run factory ammo, then leave the trigger pull at factory 9-10lbs.  If you want lighter trigger pull, then reload with Federal primers and get someone to do a real trigger job on your revolver ;)

9lb is a pretty big leap down from the 12+ they ship with.

a box stock 12lb trigger gun should light off anything that can light off.

Mine came at 10 lbs. It ran anything I fed it. It has been a great gun since day 1 and I'm sure it's stable mate (soon) will be the same.
