Here's the deal. I have a 629-4 with a 6.5 in. barrel. Here is the picture.

It shoots great as-is. But I long for something more unique. The 6.5 barrel is well ,,long. And heavy.
I handload a lot of 44 Mag and Special stuff, none of it would be considered near maximum.
When I take a 44 to the range it's most often my 4" with standard partial underlug.

The Classic series with the full lug was only made in special runs in 3" ,and many of those had shortened ejector rods.

Then the barrel lengths jump to 5" and so on.


SO ,,my idea is to snip this barrel off at 3 1/2 inches, and retain the full length ejector rod.

I would cut and crown it retaining the exact appearance of the original muzzle.
Then using the old front sight, cut it off and mount it on the shorter barrel.

I have a friend with a fully equipped machine shop, who works on his own rifle barrels,
He has the crowning tool, and would do the initial work for no charge. Leaving me to do the detail work.

The barrel markings are acid etched and could be easily removed by bead blasting, then the standard brushed finish re done.

Cost in parts $0. Outside labor $0. My time : priceless

In conclusion ; I am all but convinced I am going to do this. I only paid $400. for the gun originally.
The absolute worst that could happen? I screw up and have to buy a new barrel.

I have been a mechanic for the past 34 years of my adult life.


Talk me out of it. Or give me your yea, or Nay.

If you can remove (or live with) the barrel markings that are left and if you can remount the front sight, go for it. I much prefer the longer barrel on magnums, but do what pleases you!
 
You may wanna consider going to 4" instead of 3.5". Reason---Many states have a 4" minimum bbl length requirement if the gun is to be used for hunting.
 
I have been in the middle of a similar project. My 629 looked just like yours when I began. I bought a 3" barrel from Brownells and dropped it off at the so-called gunsmith. He bent the frame removing the original barrel. Gun is now a S&W on the gunsmith's dime to see if they can fix it.
I like your idea. I hope it works out for you better than it has for me.
I do still have hope that S&W will fix the gun. If they don't the gunsmith will be buying me a new gun of comparable value.
 
Al,
You are on to something great. My preference would be to make it 4", since they've never made a 4" Classic model (M627 that is).
You can get the Weigand front sight base in either stainless or blue that has the Classic system, i.e., it accepts the quick change S&W blades as in your gun currently.
I'd leave it beadblasted finish, and would probably send it to S&W and see if they'd roll mark some proper factory markings in the barrel, that would be cool and no-one would be the wiser.
Whatever you decide to do, enjoy it.
P.S., if you go with my suggestions, remember to think of me when you tire of it, my 4" M610 project could use a friend....

4" BARREL I've asked Smith to build the 629 classic with a 4" for years. Do it and then you can get a 625 4" for a partner. Then a 686 for a junior partner and a 3" Model 60 as your J Frame underlug special.

Build the 4" with the Weigand front sight.
 
The 4" Model 625 I had for a while was absolutely ideal as a heavy-duty sixgun. About the only improvement you could make would be to chamber it in 44 Magnum.

Allen Frame - you know if you cut front sight off and make it where you cut a 1/16 inch deep slot on the end of now new barrel, why can't you pull the front sight and drill for a 4-40 screw and tap the new barrel and the screw or screws would be hid. Guess you could sliver solider it on?
A 4 inch would be a nice size to have.
 
Update , welll ,, I have ordered the Weigand sight base, and a .200 Patridge blade.

The length is going to be 3 7/8ths. when finished. I will post on progress, and pictures as the project moves along.

Thanks ,Rob for the suggestion, now at least I know why they call you 'plenipotentiary"

Here is the update. I received the Weigand front sight assy. in the mail, with the proper patridge front blade.
$50.00 shipped.
My friend Bruce cut the barrel down on his band saw , I had the frame and barrel assembly masking taped heavily to protect all surfaces from scuffing.
The total length at this point is 3 7/8inches.

And here is an idea what it will look like. Next off to the machine shop to have the slot cut for the front sight.

Then I will finish the end of the barrel by hand with a file and a buffing wheel.

Update August 09

The Weigand front sight would not work. The reason being; there was not enough material from the top of the barrel to the bore to machine the slot and have enough material left to drill and tap for the screw.
My gunsmith explained that the Weigand assembly is for when a front sight assembly is machined off, and a replaceable front blade assembly is desired.

So ,after we discussed it ,we decided on a Millett dovetailed front sight. Just like on my P.C. 629-5.

Cost for the front sight and cutting the slot/dovetail ; $73.00

Now all that is left to do is crown the muzzle, finish off the end in a suitable manner ,,and bead blast the barrel to remove the markings.

Here are the pictures:

Are you sort of guestimating that the dove-tailed front sight will be high enough? I would think that what's left of those barrel markings could be hand sanded off, or were you going to bead-blast the whole gun? Interesting project so far. You will need the use of a muzzle face cutter to make sure your barrel is square. That tool is not cheap. Then there is the all important proper crown to make it a shooter. Keep us posted, as I like your choice of barrel length with that full-lug.
